Random Rewards Video Poker

Has anyone here done an analysis of this game? Played it last night at Red Rock, $0.25, single line, double double bonus poker. There seemed to be quite a bit of fluctuation in the random pay tables. For example, the 4Aces w/kicker ranged from $500 - $650. I used basic strategy, but wasn't sure if there were some exceptions based on the random pay tables.

Thanks.
