Comet,

A common misconception may be surfacing here:

The TGM motto -- "Sustain the Lag" (3-F-7-B) -- refers to Clubhead Lag (the stressed Clubshaft and #3 Pressure Point Pressure) . . . not to Accumulator Lag (specifically, the Cocked Left Wrist [#2 Accumulator] and Turned Left Hand [#3 Accumulator].

You 'Sustain the Lag' with both a one-inch Putt and a 300-yard Drive.
