John, I see improvement, definitely! You're not pulling the ball down near as much... and yes, you are coming around it a bit early still. Knee bend is ok, just try not to stand up out of your bend until the ball is past the arrows.
You are close. Look at your hand at the point of release on your back-up ball spare shot.... your hand is in the perfect strong, work-the-inside of the ball position. It's right there for you. You've already got it! Now, instead of sweeping your hand up the left side of the ball... from that back-up ball position, bring it right up the back of the ball. Don't even try to turn it at all for now. With your fingers under the ball at 7:00, bringing them straight up the back will automatically give you a few degrees of rotation.... enough to engage the core. You should see more revs, but maybe not a lot of hook, yet. Later on, you can experiment with more rotation... when you're used to not turning it early.
