Yeah, one of VPFree2's many faults is that it doesn't always evaluate less-than-fullpay schedules accurately. To be precise, every 1-unit reduction in the quads payout costs you 0.96%. A 2-unit reduction costs you 1.92%. Subtract that from the 100.65% return of the 20/7 game and you have 98.73%.

 

More of an academic exercise than anything else since there are only a couple more JW machines than unicorns in Vegas.

 

It's kind of odd that the three times I've wandered into the Plaza to play that one ancient 20/7 game, no one's been on it.
