Is it possible to get cache planters for the last year?

During the past year (21 July 2010 to 20 July 2011), a total of 2077 caches have been planted in Africa, which is 23% of the total over all time. This gives an average of 5.7 new caches per day in Africa, of which 4.9 are in South Africa. (A year earlier the rates were 4.6 and 3.9 respectively.)

 

The top planters for the last year are:

1. paddawan: 95

2. GEO936: 83

3. louwtjievdw: 83

4. Wazat: 65

5. Fish Eagle: 44

6. MadSons: 43

7. TechnoNut: 42

8. NotBlonde: 39

New caches per province:

During the past year (21 July 2010 to 20 July 2011), the number of new caches planted in each province:

Gauteng: 533

Western Cape: 441

Kwazulu Natal: 313

Mpumalanga: 126

Eastern Cape: 121

Free State: 113

North West: 75

Northern Cape: 37

Limpopo: 28

Cache density per province:

The densities of active caches, expressed as the number of caches per 10000 square kilometers, are:

Gauteng: 700

KZN: 109

Western Cape: 107

Mpumalanga: 69

Eastern Cape: 36

Free State: 28

Limpopo: 21

North West: 18

Northern Cape: 3

 

South Africa: 53

Rest of Africa: 0.33

 

The density for the USA is 539, and for Germany it is 5543. (This means that for the same area, Germany has 105 times as many caches as South Africa!)

 

Another way to look at cache density is to calculate the average distance between caches, assuming they are evenly (and optimally) spaced. The average distance between caches in South Africa is then 14.8km, and for the provinces:

Gauteng: 4.1km

KZN: 10.3km

Western Cape: 10.4km

Mpumalanga: 13km

Eastern Cape: 18km

Free State: 20.3km

Limpopo: 23.7km

North West: 25.2km

Northern Cape: 63.4km

 

Rest of Africa: 188km

Germany: 1.4km

UK: 1.7km

USA: 4.6km

Australia: 17km

Thanks for the great stats Danie! It is very interesting....we have come a long way over the years.

We are so thrilled to hear about the cache density in Germany....we will be going there soon and we are so looking forward to it!

I have been wondering about something. Does the Pareto principle apply to caching (with respect to hides, and maybe finds)?

 

Have 80% of the active caches in SA been placed by 20% of the cachers?

And, (unlikely) have 80% of the finds been made by 20% of the cachers?

 

When there is time ..... :)

It would seem that the number of caches placed in Gauteng just doubled over what was placed in the last year.... In TWO days. F&$@

It is even more - the increase in Gauteng in one day (640) is the same as in the previous 1075 days (almost 3 years)!

The increase in South Africa today is the same as the growth since 26 January, i.e. 178 days (6 months).

How come? Please share.

The Gauteng Power Series (about 640 caches) was published today.

I see that some were logged yesterday... that is cheating... hee hee...

Gauteng Power Series statistics:

The western loop has 252 caches over a distance of 58.3km, for an average of 1 cache every 231m

The eastern loop has 402 caches over a distance of 97.9km, for an average of 1 cache every 243m

In total there are 654 caches over a distance of 156.2km, for an average of 1 cache every 239m

(Another 20 existing caches are very close to the western loop, and 93 existing caches are very close to the eastern loop, for a total of 767 caches.)

 

The 654 caches were hidden by 31 cachers (each about 21 caches over 5km).

 

There are 600 micros, 44 smalls, 9 others and 1 regular cache.

 

One of the 654 caches has been temporarily archived.

 

(I shall later give the number of finds, DNFs, and who has found the most.)

Some time ago I published graphs showing the find distribution - there definitely was a Pareto trend, but if the numbers were 80 - 20, I do not remember. I'll redo that one and have a look at hides as well. (I suspect that much less than 20% of cachers have actually hidden anything.)

Link to comment

Looking only at currently active South African caches, all 6431 of them have been hidden by 843 cachers.

These 6431 caches have been found by a total of 6417 cachers. (It is interesting - this almost 1:1 ratio of caches to cachers has stayed the same from the very beginning.) This means that all the caches have been hidden by a mere 13.1% of the cachers (or to put it differently - 87% of cachers have never hidden any caches. Some of them are tourists, but it still a surprisingly big percentage.)

If one only counts those who have actually hidden something, 80% of the 6431 active caches have been hidden by 24% of the cachers who have hidden caches - close to the Pareto number. (Half of all the caches were hidden by 6.8% of the hiders.)

 

80% of the finds of currently active South African caches were made by 13% of the cachers. (And half of all finds were made by only 2.6% of all the finders!)

Thanks Danie - was more or less what I suspected. You just cant get away from Pareto :)

 

Now, I am wondering about other countries ..... But I know you don't have that in your db.

Now, I am wondering about other countries ...

The numbers for USA hiders are quite different - they have a large number of extremely active hiders. There are 5 cachers in the USA who have hidden more than 1000 caches each, and the top hider owns 1575 caches. (More than all of the Western Cape. How on earth does one maintain so many caches?)

There are 108144 cache hiders in the USA, and 80% of the caches were hidden by 10944 of them, or 10.1%

There are 127520 cache hiders in the rest of the world, and 80% of the caches were hidden by 42.9% of them.

Dates for South African 995 cache PQs

 

Please can anyone help with a list of to / from dates to give +/- 995 caches per PQ for South (or Southern) Africa?

 

I have been structuring my PQs around provinces up to now, but think it is time for a change ....

 

TIA

 

PT

 

Later Edit - Flying Syringe pointed me to a GSAK macro that does this very well.

 

GSAK Macro

Edited by TechnoNut
Link to comment

I was working on date ranges but opted to go the provinces rout instead as the date one gets messy when you are forever having to change it all the time to accomodate new caches or unarchived caches... The Macro is going to help, but you still going to have to adjust all the time.....

The macro works for provinces (countries) where there are more than 1000 (or 500) caches as well - or any filter you set up in GSAK.

 

So, set your filter, run the macro and it will give you the breakpoints for that filter. Nice.

10 of the caches have 0 finds, but 4 of these are temporarily archived, and it appears as if the other 6 are missing as well.

 

There have been 122 DNFs.

 

309 of the caches are within the municipal boundaries of Pretoria

237 are in the West Rand

Cache sizes:

There is a definite trend towards smaller cache sizes. First the distribution of sizes of all African caches over all time:

Virtual: 0.3%

Large: 0.7%

Other: 3.4%

Not chosen: 5.8%

Regular: 19.0%

Micro: 34.4%

Small: 36.3%

 

For only the last year (11 August 2010 to 10 August 2011):

Large: 0.5%

Other: 4.1%

Not chosen: 6.6%

Regular: 6.6% (12.4% less!)

Micro: 51.7% (17.3% more)

Small: 30.5% (5.8% less)

 

If this trend continues, regular caches may become as scarce as large ones!

Danie - is it possible to drill down more on this? e.g. Of those who have placed 5 (or 10) caches in the last year, what percentage of their placements have been large/regular/small/micro etc?

 

i.e Cacher Name, 20 placements, Micro 50% Small 30%, Regular 15%, Large 5%.

 

Then we can see who is putting down all the micros :-)

Hahahaha thanks Danie... You made my day! :) Sadly I must admit that the true number is only 1 given that the cache was published, archived and then re-published with a simpler mystery.

 

I absolutely love your stats though - makes for interesting lunch time discussions whenever new ones are posted. Keep up the good work.

 

May I ask how you managed to generate pocket queries for the whole of Africa? Is this also done by grouping caches into pocket queries by date interval?

No, you can get the whole of the rest of Africa in two PQs - there are currently about 1008 active caches. To generate a PQ which covers more than one country, keep CTRL pressed while you select the African countries one by one. (This is a trick I learnt from Jors!)

Gauteng Power Series statistics:

Up to this morning (17 August 2011) there have been 10252 finds of the 655 GPS caches, for an average of 15.6 finds per cache.

There have been 337 DNFs on 138 caches.

The most found cache is GPS - Solidarity, with 55 finds.

There are 5 unfound caches, of which one has been archived.

 

20 cachers have found more than 100.

58 cachers have found more than 10.

142 cachers have found at least one.

From the above numbers it is clear that most of the cachers do not try to do large numbers in a single outing.

The average number of finds per cacher is 72.

 

It took from 14 January 2001 to 8 December 2005 (almost 5 years) to get the same number of caches published in South Africa (655) as are in this series.
