I see when you run the adaptation a couple different percentages are shown. what do these represent? I normally see about 12-16% and around 84-89%. what do these correspond to?

The throttle body uses a pair of potentiometers to measure the angle of the throttle plate. The potentiometers are oriented opposite one another, so as the reading from one goes up, the other goes down. This is a redundancy feature in case one potentiometer fails. There is a similar pair of pots in the accelerator pedal. Anyhoo, the deal with potentiometers is you shouldn't use the very lowest or highest areas of their range. Potentiometers become inaccurate at their extrema. So, the range from closed throttle to WOT may go from 12% to 88% or something like that. I would never expect to see 0% or 100%.
