If it has to be felt, what does a feeling look like?

How many data points would be needed to distinguish between good posture and bad. Proper technique and poor?

There are now sensors small and cheap enough for small budgets to create a picture of how various pieces move through space. How many would be minimal for a sort of standard?

If you wanted to "record" a technique or feeling, how many places on the body would you expect to record? Each sensor records 3axis acceleration and 3axis angular rotation.
My initial list:

One on both sides of the knees and elbows. 8 +
left, right hip. 2 +
left, right shoulders. 2+
head 1+

so a baker's dozen sensors placed over the body to get a crude picture of movement of the entire body... ?
