Auto tune.
As hard as I try I can only hit about half of the cells when running auto tune with my power vision. Is there any tricks to be able to hit more cells? Wish there was a dyno tune operator in my area that knew how to use a power vision. Just might have to take a road trip to wide open cycles.

While no one can hit every cell, if you use hills/brakes/patience, you can hit a bunch. What Chad can do in a few hours would take you days, and some spots you'ld still miss 
It would be worth the trip and $ spent just to watch him work. Your bike would be happier as well.

It's not just about getting the hits in the cells, it's getting "good hits" which is very hard to do on the street. Think of the cell as having a center, top, bottom, left side, right side and also the corners. The closer you can get to the center of the cell the better the data will be.

I always suggest to take the bike to dyno tuner, autotune function will use the narrow band it will set/adjust the AFR/VE's to 14.7, this can cause damage to the engine if you hit the high KPA's lets say from 70 to 100, if you have AT100 this can do the trick tune the high KPA's with wide band and close loop area (cruising) with narrow band.
However, even if you have the tools still recommend to visit dyno tuner, its not possible to hit all cells on the road and monitoring PV (tinny screen) also please think about your safety!

Is this why when using an "autotune" function you try to get a large number of hits in each cell? the more often you hit a cell then there is a better chance for good data? How can you tell if you're not getting good hits? Is that when you look at the new VE and one particular cell is drastically different than it's neighbors?

no different than using brand x 10w40 motor oil in your bikes. It will certainly work, just not ideal.
