Well, I read the last article, it was very informative, I hadn't seen this article before, thanks for posting it. But it still doesn't make complete sense to me yet. ... I can understand the reason why it works on a flat top going from .060 to .040 . But I dont understand if you take these 3 pistons show here wouldnt all the quench or squeezing area be the same?

just hypothetical numbers here for example

piston 1 = .000 deck height -10cc 10:1 compression

piston 2 = -.050 deck height -5cc 10:1 compression

piston 3 = -.100 deck height flat top 10:1 compression

All have the same amount of compression area. Turbulence would be the same for all 3 pistons wouldn't it? They all have the same size cc chambers.. If these were all flat tops I can understand quench improves because you have less cc'ed area, but if you are limited to say 10:1 compression, arent all 3 pistons going to react the same? If nothing else piston 3 leaves more of the fuel air mixture closer to the head then piston 1 because its spread out over the entire piston top.
