Levelling Up

THIS is usually a quiet time for club chess, but the new Summer League - its inaugural season was last year - meant I played one game for Battersea this month.
By beating a 176, I finally levelled my first-season number of wins and losses for Battersea.
My updated club stats (CLL is Central London League; LL is London League; SL is Summer League):

*Opponent has no official grade. Last published grade was 172 in 1997, which was pre-recalibration, and he was in the 180s before then.
Overall for Battersea I am +9=6-9 for a grading performance of 173.
