All of this seems silly. Find the cache, log it, and move on to the next one. It's not a numbers game, but it's still fun to watch the numbers. I'm new to this, and there might be reasons to double log a cache, but I can't think of any.
We are only logging our finds once. We're only logging trackables we have in our hands. And we'll only be watching our own numbers, because who knows if other peoples are accurate.
Rules shouldn't need to be more established because people should play with respect.
