Are you totally missing the plot here mate? There 150's but get 165 on the new system.

No, I dont think so! What I am saying is that there is something wrong with your maths. If you played 150 (old grade) players and nearly always beat them (I assumed that to be scoring 90%) then you would yourself be graded 190 (old grade). But you're not. So either the average grades of your opponents is lower than 150, or you dont win nearly all of the time.

Either way, if the actual average grade of your opponents and your score against them was properly known, I think you would the new system grading performance would look far more accurate.

From what Ben has said earlier, he has recently graduated and moved to a new area. This is his first season playing for Hayes, presumably in the Hillingdon, Thames Valley or Middlesex leagues. So he didn't have any last season results against opposing 150s for comparison. By contrast his current grade (176/179) would have been mostly earned in the 4NCL and international tournaments.

Fair enough - in which case three games this season against 150 opposition is of course not enough info to draw any meaningful conclusions.
