Pressure points don't unload until after impact in an ideal stroke. You may have just been made a quick post oversite however taken the wrong way by any particular reader - the results are disastrous. Delay in the onset of "release" is the proper termnotunloading which refers to pressure points.
Put another way, constant pressure of a pressure point to their assigned accumulator doesn't prevent the release of the assigned accumulator. Since a loss of pressure point pressure would release an accumulator, one might think that on the opposite end of the scale that constanct pressure would not release accumulators - which is not the case. Pressure of Pressure points do not impact or control the type of release in an ideal swing.
