Ooh, you should check out tagtime on github—http://tagti.me—and see if we can join forces on this. I think it’s important to have Poisson-distributed sampling because otherwise you can anticipate the next ping and insert a bias into the tracking (even if you’re trying to be perfectly honest—in fact, you might try too hard and overcompensate, inserting the opposite bias). If the pings are Poisson then that’s impossible.
The original reason for the 15 minutes sampling was due to how we do billing, but I’ve never tried to “game” it, and if I’m distracted enough to be able to anticipate the next ping, there is something seriously wrong with me since I’m clearly not focused at all. :) If I work on two projects during an interval, and am not sure (roughly) how I split my time, I’ll split it even. It’s worked out pretty well.
I’ll take a look at tagtime at some point next week. I’d guess that there’s a way to tune lambda based on the minimum feature size you’re trying to capture, right? It’s been a while since I’ve dealt much with Poisson distributions, and never had to generate them.
