what is the best way to practice to achieve Phil's impact alignment?

Drag the Wet Mop with your Pivot. I know that sounds like a broken record. But you can't get there with effort from the arms or hands. The Power Package (for a swinger) needs to be pulled so that the hands are in the line of sight to the ball before release.

And a daily dose of LBG, as Drewitgolf said, will help.
