The GB Pro at my location doesn't have any noticeable SDTM problem. Honestly the biggest SDTM danger seems to come from cradle attempts. Otherwise drains are usually from hitting the metal rails and bouncing down the outlanes, or air balls sailing above past everything on their way down. This table has been the #1 earner in the weeks it has been here. I'd say it's less frustrating for civilians than AC/DC or Walking Dead.
Definitely agree with the right ramp criticism though.
Quoted from kpg:If anyone is putting up big scores and having longer then 15-20 second ball times with the factory gap and no center post, they need to compete with Keith Bowen in a tournament then. Average players simply will not do well the way it is. Even with the center post the game is still very challenging with the huge gap.
I'm an average player and put up 1.3 bil the other day. Another average player put up 1.6 bil the next evening.
