That's my understanding. It's a pretty different game when you think about it. It will reward different people.

The scoring system is extremely non-linear. Having the top post/comment matters a lot, plus that would mean all other posts from throughout the month will become worth less, because their ranks are being reduced.

Also, zapping the top posts/comments early matters a lot. So, if those posts/comments haven't happened yet, then neither have the early zaps on them.
