Enjoyed watching the vid, good angle and some good hitting..
I would suggest at that warm up level 3.5 only because it seems as though when it mattered to actually go for hit think I seen it once or twice you hit it long..
I think when you record a vid and have like a tie break to 10 and you will see then how much different it is and people will be able to give more accurate rating..
That court does seem to be fast or is it just me?
Enjoy the tennis
