I think the PWR slider *IS* the computer soundcard level.  I set the PWR slide to reliably trip the Signalink PTT and just a little more.  This puts the TX level on the Signalink between 9 and 12 oclock and allows a smooth control from a max of 100 watts down to zero on my TS2000.

That being the case, then why is the PWR slider in the WSJT-X application available for use in both the TUNE and TRANSMIT mode and why does the application allow for saving those settings?

Thus if the PWR slider is set to a maximum of 0 dB, then the computer sound level must be reduced to a much lower level.  And/or the Line gain of the transceiver be reduced to a much lower level.   In these instances, the granularity of the adjustments becomes significant steps in terms of level adjustments. 

Guess I don't understand your point and thinking.

First, set the "Pwr" slider on the Human/Machine Interface (HMI) to 0dB and never touch it. There are two reasons to keep the audio output of WSJT-X at full power. The first is that you need sufficient drive to activate the VOX of either the RIGblaster or Signalink. The second is quantization noise. Running the audio at full output reduces quantization noise.
