I am currently running a five man lineup - thus my gameshape has bottomed out at "4".
My trainees receive full training with a LVL 4 coach right now, and showed an increase of 300 points in DMI every week (19yo) (regardless of pops), the older trainees had an increase by 1300 in the first week and 1400 in the second week.
I don't know if sb. has figured out the exact formula yet...
I will get a better coach in the next few weeks and hope to see an ongoing increase in training speed and DMI development. If sb. wants to put the data I gather to use, I am willing to share certain parts of it.
