I know that my guide is too big but if someone want to go deeper in this subject, must read them all
You can keep notes if you want - you know, make some .doc of your own and copy/paste there.
So, somewhere there , I write that only the first values of the player when he comes in the market/game/academy, counts.
If you add sp, the Value increasing while wage not. Then we have a different factor that it's not the original anymore.
In another post I write that there are some players in the market, that they have a "fake" wage because of a bug of the game.
So, we have another "wrong" factor.
If I remember well, when I gave the sp to my player and refresh, the real wage appeared.
