These machines are $0.25/$1 replacements of the 9/6 progressive at the bar. These machine are right next to cashier/cage and they are in the same bank of machines as the "best 5 machines" in the house. Unfortunately, the 5 best machines are usually reserved during prime time. Since Jackson has been hit by teams of VP pro's over the years, they put in some serious countermeasures, which I can't disclose.
My friend (with his buddy who had a stop watch) reported hand speeds of 600 hands within 15 minutes!!! They did like 4 separate tests of 15 minutes each and 600 hands in 15 minutes is a firm number. That is about 2,400 hph on a single line machine.
Before I get more private hatemail -- I've been posting on autoholds, quad 7 promos, the new RV park at Jackson all since 2004 (please check the comment section at vpfree2.com). In fact, a lot of people have posted about fast meter movements, autoholds, quad 7 promo's etc. Remember when quad 7's were progressive and were paid double per my post (I remember hitting a quad 7 for about $220 so it was like ~$440 during the promo on a $1 9/6 JOB)!! Or $15,000 royals on $1 8/5 JOB. Or an extra $10,000 on Seq. RF on $1+ VP (it could have been $25,000 RF if you got Seq RF on the 8/5). Those were the good ole days.
I am looking forward to Jackson's new expansion when I visit my friends in Sacramento.
