Tommy,
The heel position may be as if not more important than distance from the heel. Great stylists on the pro tour with everything else correct have had careers they never understood as not quite that great because of various heel positions from shot to shot. This factor called posting causes various amounts of shoulder over the shot and multiple various hand release positions because of the upper body varying in relation to the base connection to the lane(slide foot).
As to being Lucky and all lefties, Don I think you are right on there. If you browse my meager profile accomplishments some would think I might be a little luckier than some others.
All I can say is that for about a week I did the two things mentioned above for about 130 out 144 balls. People who saw this thought I was someone else, much better than me! The consistency if one can do this is incredible.
Dave Davis relayed to me that he practiced these concepts in every practice session since 1957. This practice is so intent that he does not pay attention to the shot, where he is striking or anything. ONLY that he is within 2 inches of his ankle and that his heel is canted towards his swing arm.
I think some said he was pretty GOOD!
I occassionally drift into that zone of competance but usually just when bowling games against my powerhouse son!
He is almost scared on those days. Not much!
REgards,
