I’m just guessing but it has a lot of anti-squat and a strongly regressive leverage rate in the first 50mm of travel, hence I felt a lighter low speed compression tune. Normally the high speed compression is to stop harsh bottoming or blowing through the travel, and as the leverage rate is linear for the rest of the travel the linkage won’t hold the bike up so it might need more damping. However you don’t want too much HSC or it’ll choke and feel harsh on small but fast hits. It definitely needs some kind of ramp up on the air spring.
Not sure about the rebound, that varies more with rider weight and air pressure.
