Default PCV Autotune AT300 best practices?

When researching fuel controllers I found bits of advice regarding the use of AT. Now that I installed it, I cannot find those threads - I suppose it's the three-letter min search restriction. I hope by spelling it out in the title others will be able to find this thread when needed.

1.) If I understand it correctly, Autotune 'learns' how best to achieve the AFR targets set up in its tables for the respective rpm and throttle values. These tables come pre-populated with default values which DynoJet thinks are optimal.

a.) Do these defaults come with the unit (i.e. are they generic for all bikes) or do they come from the map loaded in the PCV?

b.) I see that some of you adjust these values. Based upon what rationale?

2.) I remember reading someone stating that you should ride the bike in a certain way to best make autotune work? How? Why? Does that mean you zero out the tables, ride the bike in that particluar way, accept the trim and turn AT off for regular riding??

3.) Any other bits of advice or what not to do?

I only ride V-Twins:
Victory Cross Country Tour (2012)
KTM 950 Adventure
KTM 950 Super Enduro

This is an AFR target posted by Ashmostro. If you mimicked this for both cylinders and zered out the fuel maps for both cylinders the AT will build a pretty good MAP for itself which you would need to accept from time to time until little adjustment happens. I use a richer AFR (13.5 where it says 13.7) because of where I live so as soon as it gets cooler I'll do the same thing and build a "Winter" MAP and just change it back and forth a couple times a year or get the switch from Dynojet that lets me do it on the fly because the Summer MAP would also be a power MAP in the Winter if needed.
