No worries mate!
I'm from Guimarães, or what people usually call, "A cidade do padel". I have a lot of tournaments on my shoulders, maybe yeah, it's just stress and playing in a tournament is definitely something else but the level, from all four, hell, I am safe to say you were the best of all 4, is quite low. I see no tense balls, no heavy viboras, no damaging volleys, just look at your partner's bandeja, we usually say "Tá a bater de frente com a panela" because it seems he's holding a frying pan and just hitting flat to the middle with no agression, no placement, just to get the ball over, which, don't get me wrong, you win tournaments by passing one more ball to the other side than the opponents, but at an M4 level those "passing balls" are barely visible where I play, the bandejas are good, the viboras are strong, people have a massive grasp of what they're doing. This is why in my area M6 socials have already opened, because the M5 from before are not the same as today..
Sorry this is long, I got carried away, but yeah, if I had to sit down and watch your game without knowing what it is, I would say it was M5 110% of the times.
Feel free to DM me if you want to chat or something
