Grogu Season 1&2 force use vs Season 3

I found the way grogu uses the force differently after training with Luke quite stark. In early seasons it was very sporadic and almost always required rest afterwards. He would also occasionally lose control and resort to using the dark side when he felt cornered or under attack (or din was attacked). This current season he is using the force far more without exhausting himself and in combat he focuses solely on defense/dodging. I think this shows a lot about what Luke has taught him in the two years he was training.
