I agree. I'm no engineer, but from what I've been able to put together over the years, good engineering practice dictates that the crown thickness will equal about 7% of the diameter for a naturally-aspirated piston. The crowns on dedicated blower pistons will be thicker than those on naturally-aspirated pistons, so you would want to be adding material, not cutting material away. I don't know what the percentage of crown thickness to diameter would be with a dedicated blower piston, but common sense tells me 8% to 9%.
