adaptation adjustment

[BorisKingma]

Describe the bug

1. filled in adaptation score, from 1 to 0.5: -0.5 is processed correctly.

2. Afterwards I filled in adaptation score again (now from 0.5 to 1 again (+0.5)), and this is not processed correctly, the value on gauge becomes 1.5 instead of 1.

adaptation adjustment is currently the delta in the feedback module as: Delta = User value - adjusted model value

the value of delta should be: Delta = User value - Unadjusted model value
