I'm certainly not one who would have an idea of how to do this in an elegant way. Key Results and Team Four Paw occasionally check in--perhaps they will have an idea.
My only other ideas would require accessing old logs.
You can do that. The history of each bug is on the bugs page. But when you have a hundred bugs and each bug has many actions you have to tediously go to each bug and then hunt through page after page of logs to find the real drops it's more than I'm willing to do. In the old days I wrote programs that would do this automatically but GC changed their website to prevent that.
As an example, one of my little found caches has 31 bugs recorded. I took the first one on the list as a random sample. That bug has 165 total actions in its history. If this is typical I would have to go through up to 5000 logs, keeping records along the way, to determine if which bugs were actually placed in the cache.
It does seem to be getting rather echoey in here. I think some people have moved…some have retired…I'm not sure what has happened to everyone. Perhaps some have gotten burnt out.
In regard to your question, I don't know the answer. I suppose if you had a history of the bugs (and I don't know how one gets that), you could look at the history of the individual TB to see if they ever were dropped off.
This is getting spooky. I'm beginning to hear an echo when I come here. When I go to Geocaching, Travelers, Puzzles and maybe others I haven't checked I have the latest topic, maybe going back months. Is this site gradually (or not so gradually) going dark? Where'd everybody go?
So anyway, I would like to figure out which Travelers have actually been in one of my caches. It has a lot listed in the history but many/most/almost all have been people dipping bugs, not putting them in the cache. I haven't been able to sort the wheat from the chaff.
Anybody know an easy way to tell which travelers were ever actually in a cache?
