It is possible that another member hit at the same time ?

I thought that it took about 30 AP's to send a post 'extremeley pos' ?
I give approx 26 - 28 and send a post to 'very pos'

If you had used 25% and took it to 'extremley pos' then that implies that you have approx 120+ AP's at 100% which at the rough guide of 1% of your AP total = your 'hit' = you to have around 12 000 AP's ?
