It's all part of the challenge. Ironic I know, me being the one to post it... and then solve. I'm about half-way through phase 2, I completely programmed it, but it isn't optimal yet, I'm going to make a few fundamental changes to phase. The idea is that you can normally expect (in, say 99% of cases) the counter to have collected all 100 tokens by the end of phase 2. It should be less than 3000 days for this. Of course, this isn't, and can never be guaranteed - so after that you enter phase 3 which will basically last until the count is completed (so it'll have no set time-limit). It could still have recurring cycles, if it'd help, but I don't think it would. At the moment with my pseudo-phase two I am achieving more than 90 people on zero tokens (taking less than 2,000 days and with the counter on anything from 10 to 50 tokens) by the end of it. The way it's set up at the moment you can't expect the counter to have all the tokens by the end of it. I'm going to re-program it with more optimised rules.
