INPA EHC calibration????? HELP

[amancuso]

So I found these instructions:
used INPA
very easy to do, it tells me to set height to 707 front 709 rear
the program is so easy use

F9 to access e53, than click on the ehc-2
than hit F6 to activate
F5 to calibrate
press F1 to open the calibration and just plug in the height difference you want in MMs

I measured my heights and my back right was higher than the left so when it asked for rear L - R
I just typed in -6 for right side to raise it slightly
typed 8 on both the front because I wanted it lower
press ok

2 seconds later the airide moves and your done

F10 to exit that screen
than you just drop your bags then raise it back to normal and recheck your heights to make sure its good

My question is say my measured height is 740 in front, Does that mean I enter 33 to lower it 707? and Alternately if I measured 690 in the rear I would then enter -19 to raise it to 709. Lastly, he says "just drop your bags, then raise it back to normal". Does this mean using the switch on the dash or something in INPA?. I'm confused. Hopefully one you guys can shed some light on this.
