Depends what you deem to be good really. I was top ten in the county a couple of years ago when I played competitions but I was along way off the very top players, though could beat a couple of them through attrition/them having off days. In terms of the lta rating system my standard is probably...
I used to be fairly good when I was 13/14, played a game for the Albion's centre of excellence against Fulham, we got dicked and I realised I was way out of my depth. Decided to concentrate mainly on my tennis after that.
