Tuning Definition - Tuning To The "Knee"

I'm a little more confused now. You talk about HS 3+5, 3+10, 3+15. etc. Please explain that . My Avenge X has only one HS adjuster.
The referenced increments apply to the "Micro" hammer spring adjustment on an FX Panthera. I have no knowledge of the HS adjuster on an Avenge X but the concept is to start low and up-adjust the HS in small increments until MV does not increase with further adjustments.
