Limited gain through multiple test matches

[MC Melza]

If I play more than one test match in between regular matches the possible gain of my players seems to be limited to 1 Point.
E. g. if a player has 92 points and the first test match brings him to 93 points. Another test match shows that he will move to the next number of points. Then he still has 93 points.

Is that supposed to be this way? Then I might have wasted a lot of boss coins.

Hello mate. the more you test the same player, over and over, the less skills he gain....
