I'm new here so still figuring out this site. I guess first off I have to enter 8 contests before my votes count or I win and coins/prizes? Is that correct? Also when looking at my profile page I'm confused by some of the stats... especially my win percentage. I have entered 4 contests and I have won all 4 contests but my win percentage say 75%. Shouldn't it be 100% since I've won every contest I entered? Thanks for any info on this.

That's correct, you have to post at least 8 entries.
regarding win percentage, its combined for regular, time attack, honor. so after you post enough entries stats will show will be reflected as it should.

Forget all that "Stats" crap, just do good chops that's all that counts.
