Wrist Problems/Better Connection to Keyboard

Hi Bob! This helps, pure gold it is. Eric

Could the touchweight be the reason downweight and upweight can be different? i.e. does downweight necessarily INCLUDE touchweight, whereas upweight would not include it and therefore can be a lower value? Does my Landowska Steinway feel so good because the touchweight has been decreased? Thanks Bob for your continued patience in enlightening us dullards! AFF
