TS calculation

I think there's something wrong with your calculation of TS. It's supposed to be PTS/2*TSA correct? When I calculate that directly -using your figures- for various players I get results that are different from the ones your site shows.

(I think the error is universal, but try for instance Durant's TS for the regular season: it's given as 63.1 but by direct calculation it's 63.9)
