PP in putting
 

Noticed Justin Rose's putting routine where he was tucking the left sleeve into his armpit prior to putting every single time he putted. Seems to me he was trying to feel accum 4 or PP4.
Anyone have thoughts about this? This would be a swingtype motion in putting. When I tried this it feels tight on my armpit, distance control maybe better, but feels unnatural to me.

Hmmm got to look for that one. First thoughts......

-pivot controlled hands

-shoulder stroke
