Is that payback % adjustable.... I think so.

{spx,
     Either your calculations are way off or you're the luckiest player on earth. To have $200k in W2's with only $750k in play would be like hitting a royal every few hours.}
 
Good point! Without going to the trouble of checking my records playing $2 DDB at max play it was more like $100K in W2's for over $1 million worth of play.
 
That was on my coin in / coin out report.  I only play with my card %70 of the time. 
 
@shadowman,  I would love to see that spreadsheet you have just to see the break down. 
 
I'm working through mine and will try and post the results just for fun.
 
 
And I understand the casinos don't make the chips but they still have access to the interface to make some selective choices.
