High Net Gain

High Net Gain is a term used to describe rooms or checkpoints in which a fairly advanced player (one who can make it to 18,000 (1st endless) to 20,000 (2nd endless) distance without glitches) can gain many balls from the rooms or checkpoints. The two other classifications in terms of the net gaining of balls are Net Neutral and High Net Loss.

A good number for this in individual rooms is about 40+ or more and a good number for this in checkpoints is about 70+ or more.

Older versions
High Net Gain was more common in older versions, like 0.8.0 and 0.9.0, because of the higher amounts of crystals.
