I've hit with him quite a bit, usually about 10 minutes before we start our sets, I realized how much this helped me too late though. At first I felt honored to even get a match with a high level player like him, so I wouldn't want to warm up for very long and wouldn't want to both asking him if he would just hit with me. I felt like I was a waste of his time, so I would spare what little time I could give him.
Now that I hit a bit first I can relax quite a bit during gameplay, not only this but what I actually learn from hitting with him is ridiculous, and difficult to even explain.
I think a big problem with low level players playing with higher level players is that the low level player is trying to prove themselves. They want to show the higher level player that they can hit good shots, but this doesn't mean anything to the higher level player.
You're not going to impress a higher level player if you miss more shots than you hit. The only way you can impress them is if you actually beat them. What will improve a player's game and make the higher level player enjoy the play more. Would be if the lower level player just relaxed, went through their strokes and tried to hit the table against them. Nobody has fun with someone smashing every ball on them and just missing. If you can prove to the higher level player that you can just block onto the table, they'd much more likely want to play with you again
Whenever I say "you or your, I'm not referring to Next level even though my response is quoting him. I'm referring to anyone playing with a higher level player.
