The most i ever did in a row was 213. Cut off the top of the index finger on my left hand and was out of work for a month. couldn't use the hand so i learned to do that with the other. It was a long month.
Sounds like you don't like what you are hearing. My advice is to listen to your golf pro, not a bunch of anonymous guys on the internet.
There are a lot of people here that know a lot about the game, but we don't know about your game. Stick with it and follow the advice of your pro. It will work out.
