% pay back

I noticed last week in Dubuque, IA (Diamond Jo Casino) that all their $1 DDB machines were 9/6 but the royals starte at $6000 and each machine was it's own progressive.
 
To my math wizards that I depend on: does the higher payback increase the payback %?  I'm assuming it raises it but I never did that well in statistics class!!!!!

 That increases the payout about 1%, even with no change to strategy

jm hit it right on the head.  These games are almost positive with no strategy changes from standard DDB 9/6.  When the progressive reaches or exceeds $6079.17, standard strategy will be positive.  The strategy changes to employ are essentially to hold the 2-card and 3-card royals more often.  At the reset value, perfect play yields 100.0888% on average.

Another thing one  needs to know is how fast are the progressive meters running on these machines.   This will tell a pro alot.  I'm guessing the meters run very slow like .1% or .2%, maybe .25%.  But, who knows, maybe they're running at .5% or better. 
 
These meters will be easy to time since the machines are individuals.  Just bet one coin at a time until the meter flips a penny. Then continue betting one coin at a time counting the number of coins it takes to get it to flip another penny.  If it takes 10 coins to get it to flip a penny it's a .1% meter; 5 coins = .2%; 2 coins = .5%.  In the case of a .25% meter you would have to bet 20 coins to get it to move 5 cents.  Knowing meter speed tells one if they should monitor a particular progressive bank.   
 
In this case the game is essentially at breakeven at reset.  Bankroll requirements would be high for this high variance game.   Most pros would want a win factor so would not play at reset.  But there are other factors like what is the slot card worth.

I've always understood the 9/6 machine to be at 98.98 plus .1 for the progressive will put it near 100. Jeez,this is Shadow and new2vp territory.
