"The point is / was, from my understanding the disruption of power with a clutch assisted trans usually requires CW for recovery."

CW is not required if there is enough base clamp load. If the torque of the engine (which is what slips a clutch) is higher at take-off rpm, say 4000, and the base is just enough to hold there, then you have more than enough base pressure=clamp load at shift rpm where torque is lower.

What seems to be often done is to have the base lower than that, with the CW contribution at 4000 just enough to give a bit of slippage to prevent bogging the engine. Then, at shift rpm, the combined base and CW clamping loads are enough for full lockup. Of course, the CW contribution increases with rpm whereas the base stays the same.
