IF, and I say if, I decide to putt it I will add 2 feet to the putt distance and that usually is sufficient. However that is if it is on Champ greens and a fairly flat putt. The OP is Tour Pro so he may need to add quite a bit more for slower green speeds.
Besides needing to be a flattish putt, it also needs to be a fairly straight putt for me to consider the putter, if it has a crazy freeway of dot traffic and inside 8 or 9 yards I'm using the chip shot 90 % of the time. Any longer and I'm pitching it, club and ball combo will decide it for me though.
as always with this subject... YMMV
