The reason this compare mode is possible for WB and HSL pipette, Repair and LA adjusts is that they exist in a temporary, “work-in-progress” state (that is; at the time that any of those tools is being used) … whereas, other tools are simply ON or OFF (they don’t exists in a temporary, “work-in-progress” state).
See here for Guenter’s suggestion to provide more comparison “snap-shots”.
