I don't know...after only two days we've already lost 25% of the contest field. A smaller contest field could make for a fiercer competition though; I think somewhere between Period 50-60 might be about right for TT. The question is ultimately going to be if we have enough people in this Leap Frog to even warrant the competition lasting that long. By comparison, the TA 2015 Leap Frog that lasted to Period 100 started with 2,021 people. TT only started with 119- which is already down to 89 as of this post.
I've also noticed that more than a few people are burning through what could have been several days worth of Leap Frog trophies early on, so let me just offer some friendly advice to anyone aiming to win: this is a contest about longevity, not leaderboard numbers. Slow and steady is what's needed to win this race, so be careful you don't waste all of your trophies now, or you won't have them when you'll need them to get the lead out in the long run!
I seriously doubt I will last long, as I'm doing this for the sake of fun rather than winning, but I'm still going to make an effort just to see how far I can get. My current goal is to make it to Period 10.
