Mizunoman, there's a difference between a natural tempo and a executed tempo. Let me explain:

When you taped your 'good' swing where your swing tempo is measured ... it was based on natural movements. Your brain does all the work and you don't have to think about it, everything is subconcious.

When you speed up, normally your gross motor control is telling your arms to go quicker. It deviated from the natural tempo that is natural or bedded in your subconsious. But, it doesn't tell everything else in the gross motor to speed up as well, let alone the fine motor control like your fingers, eyes, ears (yes, ears are very important to the swing!) ... so what happens - no tempo, no rhythm and a bad swing and probably a bad result. Why? A quick tempo isn't your natural style.

You struggle with quickness yourself not because the tempo is fast ... you struggle becuase the tempo on a 'bad' swing is not the same as what your golfing brain is used to so the sequence of events is out. If everything in your swing was sped up euqlly, you wouldn't have a problem.

Al has a naturally quick swing which he can't develop a rhythm with because the timing of transition is out. It's actually the other way around: the timing of his transition is out of synch with his natural tempo.

Natural tempo is everything ... it controls what, how and when.
