Expected winrate from defective coin slot machine??

[mattyG]

I was playing tonight on 50 cent (two coin max) slot machine in Hammond, Indiana..after putting one coin in by hand, I was consistenly having two coins registered for play...with only one coin in!!If the coin did not register for two coins and I inserted another it would be returned after spin. I know the payout on these machines is approximately 92.6%..please tell me if I am only paying for half of the max coin-in which I was paid out on, what is the expected return...is it as simple as multiplying by two?I made $190.00 in two hours and no, I did not rig the machine [img]/images/graemlins/laugh.gif[/img] [img]/images/graemlins/laugh.gif[/img]
