I looked into it some more and with the very easy compare option of HO I've found some more cases. Weird though as the rules say only players who actually play get training. The example that's in the rules section basically says :
- played position according to training : lot of training
- played other position : a bit of training
- didnt play : no training
So apparently the example is wrong
