Here's a thought... Having advantage and being able to enter contests early is great, but there's one little negative detail about pre-posts. They reflect badly on one's stats. The most clear effect is that they count as submitted entries with zero votes so they bring down the votes per post and, concequently, the PSCore. Should that be the case? I mean should the number of votes of an entry that can't be voted for count?
I rarely paid attention to the stats on my profile until I heard they're used in assigning an H2H opponent.

Ignore the stats and concentrate on winning?
