when the track of the ball goes over the thumb hole does that mean the person is a full roller???

I think its when the track actually goes in between the thumb & fingers.  I could be wrong though

If you mean clipping, then no.  If the track is completely through the middle of the span between the fingers and thumb, then yes it's a full roller track.

generally, a full roller tracks between the fingers and thumb hole, providing the person is throwing a ball drilled with a full-roller layout.  If a full-roller is throwing a normal layout ball, then likely they will track over the holes.  Likewise, if a 3/4 track bowler throws a ball w/ a full roller layout, the ball will likely roll over the holes.

No.  Full rollers have a track that goes between the fingers and the thumb, maybe just clipping each on the way by.  You won't see lots of flare lines on a full roller - it rolls on the same circumference every time.  The true full roller covers the longest circumference possible on the ball.  

Now what I'm wondering is this: if someone has a track that meets all of the above criteria other than being between the thumb and finger, nearly touching both, could it be called a full roller?  Could you have an inverted full roller? (track from outside of ring to the other side of thumb?)I've seen some pretty strange tracks that cover a lot of ball surface, but do not meet this criterion.  (I recall seeing a picture somewhere of a track that was nearly parallel to a line drawn across the top of the finger holes, for example.)

I think that's a lefty full roller...

My teammate is a lefty full roller cranker (if you can believe that).  I would guess he's around 19 mph and 450 rpms.  On stuff that I have drilled leverage for him (pin 3 3/8" beyond his PAP), he gets around 4" flare.  On the arc equipment (cg in center of grip and pin next to thumb), he gets 2-3" flare.  The bowtie of his flare is under the fingers, so regardless of amount of flare (at least up to around 4"), he doesn't clip fingers or thumb holes...

Guys, I use a full roller drilling on most of my balls. The reason I use them is that without them I am guaranteed to roll over some finger or thumbhole or both. I've drilled a lot of stuff pin above and between fingers(5&3/8" pin to pap for me) and this always hits some if not all of the holes. Using a full roller drill actually changes my track that much that the track will roll between all the holes.The point being that the drilling is what really changes my track.

A full roller is someone who rolls over the entire circumferance of the ball, no matter where he rolls it (i.e. a 3/4 roller could technically be a full roller). However, full roller has come to be known as someone who rolls between the thumb and finger holes.
