On the face of it, the assistant coach's level has a slight impact on the effectiveness of training sessions, but does it also have an impact on XP's acquisitions in matches and also on match statistics? It would be logical if it did, but I don't think so.

myforsans: A priori le niveau de l'entraîneur adjoint a un léger impact sur l'efficacité des entraînements mais est-ce qu'il a aussi un impact sur les acquisitions d'XP en match et aussi sur les statistiques en match ? Ce serait logique que oui mais je n'ai pas l'impression.

Its impact seems to be more to do with the cost of individual training, I haven't noticed any difference in match wins, but you don't see many decimals, so maybe it's just a very small gain?

Yes, I've made more or less the same observation, and it's all the more difficult to appreciate that there's a small element of randomness in the effectiveness of training (unless it's the physical condition that's taken into account).
