Xcelorin throttle limits question . . .

[Bravo]

OK one last Q (hopefully!).
I got my LED on my USB adapter to turn green.
That caused a massive nights partying so haven't plugged it into ESC yet.
I find the instructions equivocal. It say "Use this to limit the power available using forward throttle. The lower the percent the less forward throttle speed will be available."
But then (in the tables) it says 0% = 100% of forward speed ! Well, you can't get any lower than 0%. 0% should be NO forward speed, not 100% !
So, if I want 80% of forward speed, I set it to 20%. Is that right ?
