I went back and played another 3 hours in the promo ($2 coin-in is 1 point). The game is a $0.25 triple-play machine. In my prior thread, only a couple of keen people caught what was going on.
Today, I averaged 3,000 points an hour playing one machine. That is $6,000 of coin-in, and that translates into 1,600 *decision* hands or *base* hands per hour at $3.75 a spin ($6,000 divided by $3.75 per spin is 1,600 decision hph). This 1,600 rate was sustained for 3 hours without bathroom breaks, without looking at my strategy card, without buying drinks from cocktail lady, and the only break was the 3 bonus hand-pays. The 1,375 decision hph in the prior trip was just a test run.
Lots of people were playing faster than me and I guesstimate the lady to my left was playing at 1,800 decision hands per hour. This lady stopped in her current mid-hand as if hit by an epiphany. She realized she had drew to a royal flush in spades (in the prior hand), which vanished when she played her current hand. She confirmed this when her credits were $1,000 higher. She looked at me and said I didn't realize I had hit a royal. To which I kindly responded: "Lady, I wish I had your problem."
The good news is that I hit 7 bonus hands instead of the expected 5 during my two trips. However, I would have rather hit a royal.
