As a 7-6 it is difficult to get the high marks, as you won't have those type of games.
Looking at the marking, I think that the Section 1 should be a 4 from what is written but it is a judgement call and not obvious
The important for a 7-6 is to learn and get better in the next assessment so the corner positioning and other development points don't reappear.
Matt it may be worth writing a nicely worded email to your RDO asking for an appeal on the mark given. It certainly won't do you any harm!
