This number means he's running really good. Don't expect that one to hold up as you get a larger sample size.
Raise more often preflop, for sure, and I like to play more hands too, but I know nits like JD have success playing super tight

so I'm sure you can too.
Edit: Didn't realize thid was full ring. My comments hold up, except for the play more hands one. Just limp in a little less and raise more often.
