The infamous "one piece takaway" has helped hackers and ruined players. Swingers take the club to the "end" rather than the "top". The load against pressure point #3 at the end is easier to accomplish with a snap loading procedure 10-22-C in the backstroke which delays the lag loading at the end until the last instant.

Hey Bagger!
Help me out. When you say 'end' rather then 'top', do you mean 10-21?
The lagging takeaway combined with a Swinging procedure and a BS which ends at or before the Top, facilitates downcocking. This can be especially useful for players with a very limited range of motion to get more "snap".
