Dead bounce more. I had a buddy over yesterday and we played plenty. I noticed he NEVER let the ball dead bounce off a flipper. I was wiping the floor with him scorewise, then strongly suggested he try harder to NOT flip. I swear, once he got his head around it and controlled the urge, he was INSTANTLY a better player. Scores matched up from then on. Amazing how binary the improvement was. Obviously a sample size of one is not statistically robust, but we both agreed it was pretty clear. He remains a better drinker than me.
