As @alexlifeson says, 9/6 doesn't apply to every machine. The first machine he took a pic of, the top payout is 9/5 (99.69%), but the bartop is only 9/6/5 DB (97.81%). I honestly would have played at another bar if I was concerned about return. 8/5 Bonus (99.17%+prog.) at "Rocks Lounge" for example.
