I'm not sure how you could be a member of this ladder for several years, when the game site has not existed quite that long.

As for 30 in the TOC, I think that is likely to be accurate. The TOC, while held late, was for winners in June, and player participation was certainly down during that period courtesy of a lot of churn within the TD ranks. It is also not outside of the realm that some winners may have either withdrawn or been purged from the ladder between their win(s) and the actual holding of the TOC. I would wager to say the 30 eligible players was an accurate count.
