In an attempt at a more scientific estimation, I took the info above and plotted it on a

graph like so:




I did not quite know how to interpret and extrapolate trendlines using the Excel serial dates, so I converted the dates to "days after 20090505" - the initial date in the list above. I suspect that cache placing should decrease because it is winter in the Northern Hemisphere (where most of the caching activity takes place), but the graph does not show much of a trend to reflect this (then again the time span only includes the "good" caching season for the northern hemisphere). I added a polynomial trendline - a bit more flexible than a straight line.


That polynomial predicts 10E6 caches at 288/289 days after 20090505 = 20100215. I will add another month due to reduced caching activity in the northern hemisphere, so my educated guess is 20100315 or 15 March 2010. I'm thinking April 1 2010 is not a bad guess at all.


Way back in November I did this study in a post the main forums


There I predicted 15 March 2010

In the very first event cache we attended Let's Quiz again like we did last summer in June 2007 one of Discombob's questions was what were the active caches and number of logs as displayed on the main page at the time. Then it was something like 457,000 caches and 48,000 logs - almost 3 years later and now it is 989,000 caches and 1,914,000 logs!

Are we allowed to give a few options to our predictions? Like...


2 April 2010 (because that is my Father-in-law's birthday), if not reached by this date, then:


3 May 2010 (Rolf's birthday), if not reached by this date, then:


28 May 2010 (My Mom's birthday), if not reached by this date, then:


18 June 2010 (My Dad's birthday), if not reached by this date, then:


26 June 2010 (Nadia's birthday)
