I don't think it does, though. They figure out the average number of putts from each distance. So the average on one foot putts would be very close to 1.0 while the average on 40 foot putts would be more than 2.0. So they're only comparing how many putts it took you to get down from a certain distance with the tour average from that distance. Thus, it doesn't matter how close to the hole you start.Strokes Gained-Putting
The statistic is computed by calculating the average number of putts a PGA TOUR player is expected to take from every distance, based on ShotLink® data from the previous season. The actual number of putts taken by a player is subtracted from this average value to determine strokes gained or lost. For example, the average number of putts used to hole out from 7 feet 10 inches is 1.5. If a player one-putts from this distance, he gains 0.5 strokes. If he two-putts, he loses 0.5 strokes. If he three-putts, he loses 1.5 strokes.

I was wondering how they came up with this stat. So I looked it up. Still, a player's iron play would affect their stokes gained putting. Not all 10 putts are the same.
The only difference is I don't know how long an average they take it over. A 10 foot putt on one green is not the same as a 10 foot putt on another green. So I don't know if the average is just for that tournament, for the year or how long. So there may be some slight variation but it would be pretty insignificant except on a course that has a lot of extremely tough or extremely easy greens (if the average is for longer than that tournament).
