The 'TND' fields is really just my version of the Tendex rating system. Based on the approximate Point-Per-Possession, each statistical category can be related to the game's scoring. Every time you make a basket, you have made 2 points for your team. Every basket you miss, you lose possession, and subsequently lose 1 point for your team (of course, if a team member gets an offensive rebound, that player will gain possession, and 1 TND point).

Players who have a higher TND value than their scoring average will tend to contribute to their team in ways other then scoring (i.e. high assist or rebound players). While the opposite suggets players who's job is mainly to score.

While I IN NO WAY, claim this stat to be an end-all way to rank all the players, I use it to give another data point as to how well a player is contributing to their team.

The current MyTendex formula is:

(PTS - FGmsd - FTmsd/2 + 0.5*m3 + 1.25*st + 1.25*as + bl + reb - 1.25*to - tc - 2*ff - pf/2) 
			         / GamesPlayed

There is also a TND value normalized to 48 minutes.
