The Lsc & Hsc work in conjunction with each other .so if you want more lsc add hsc first
Yes I believe it is one of the quirks of the damper, something to do with shim stack pre-loading IIRC.
You will notice when the HSC is fully open the LSC doesn’t do much. Apparently it becomes increasingly effective with each click of HSC.
When I’m pump tracking or jumping I have both fully closed!
I’m afraid all but the latest Mattocs have the same design fault that afflicted early Mezzers. Excessive bushing play is common with Mattocs and Minutes IME. Often it’s not noticed by users because, in the main, the damping on the pro models is pretty sophisticated, especially when coming from more basic forks from other brands. The forks when new are also packed with grease, which keeps it quiet!
If your fork has bushing slop it feels like your headset is a tiny bit loose. Put your bike on it’s back wheel and bounce it up and down. You will hear a buzzing vibration/rattle through the fork and you can feel it’s at the stanchion lower junction with your hand. On the trails it manifests itself as stiffness/binding on fast washboard sections.
