Right hip and foot action during downstroke.
 

What do you think about focusing on a turning right hip and knee action to ensure a turning torso through the impact interval? I used to be a little flat footed with my right foot through the ball and it would appear through my right ball flight I was using angled hinge, but NOT so according to video.
Does this basically mean a poor Zone 1 / Pivot can hinder a perfect hinge motion and make an Instructor think your using angled hinge when actually your not.
When I focus on turning my right hip through the ball and the right fooot coming up I hit a tight draw. I guess this means I'm pivoting correctly and Zone 1 is better? This explains why Homer advocates mastery of zone 1. Right?

If you look at the golf 'swing' as a flow of motion, that creates and maintains lag, you can compare it quite nicely to a whip being cracked.

Zone 1 - Pivot - is IMO even MORE important for swingers than for hitters.

When you have a poor pivot, you are trying to 'crack the whip' but you aren't starting the whip motion at the handle (the feet), you are in effect trying to crack a whip by starting it in the middle, or to take the analogy further, by trying to crack the whip by HOLDING it in the middle - totally out of the 'sequence' that simply must be there for a proper whip motion.

Hitters can get away with 'less whip' because they are in effect using only the 'last links in the chain'. They have a 'shorter whip' that can, and often does, start higher up the 'sequence'.

By firing your right side as you describe, you are doing a better job of 'starting' that whip motion from the 'ground up'.

The best way to really get the feels for this is to do pivot drills without a club, arms folded across your chest (right hand on left shoulder, left hand on right shoulder).

An image that I find very powerful is to imagine that you have a wall just inside the left foot that you are standing perpendicular to. Drill trying to 'break down' the wall with the back of your lead shoulder. Really get into that image and feel the power you can obtain by 'bracing' and pushing off of the right instep. Work on the 'unwinding' in slow motion as well - left knee, left hip - feel the stretch in the left side - left shoulder, arm, club etc.

Then try hitting a few of your '160 club' only 100 yards, using the back of the left shoulder as your key. If you find that you hit pulls, imagine the wall is angled a bit such that you have to go 'out to right field' - until you can hit a sweeping hook by hitting DOWN on the ball.
