Affirm/Cynosure Smartskin+ CO2 Max Ablation Depth

I was wondering if anyone happened to know the max ablation depth (at aggressive settings ie treating acne scars) of the smartskin+ co2 laser? Some of their documents state 300-350 microns, whereas some state 2mm using their "multiple pulse" tech. Is it actually able to go to that depth? Adding onto that - is there any difference between a multiple pulse system (ultrapulse/smartskin) vs a single pulse system (re:pair/deepfx) when treating something that needs more depth?
