And not uncocking it (more than level) is also a problem?

Ideally one establishes the wedges, angle of approach, level wrists etc at Impact Fix, not returning to this at impact compromises the quality of impact.

I guess one could choose to have the wrists slightly cocked at Impact Fix but if one assumes that the left wrist is still fully uncocked at Follow Through then it changes the rate of uncocking through the impact zone and I don't know if one can maintain the sweetspot on plane in that case.
