I've been experimenting with this at the range after watching the videos. Applying the same lag pressure, the difference between my punch and when I go to the top is at most 1 club (depending on ball position and trajectory). For me, there is no discernable distance difference between end vs. top; if anything I hit it consistently purer, straighter, further and with better trajectory and sizzle when I stop at the top.
So why go to the end??
Would love to hear some more input on this as well. BTW - I meant Acquired Motion, not Basic Motion.
