From what I understand of the assessment system, getting a combination of standard expected/above standard in a challenging match is as good or better than getting above standard across the board on a regulation match. I have to admit to being a little surprised that a match with a single, generally accepted dismissal and no cautions counts at challenging, but that's a side note! It's also well written and very clear on what is good/bad - perhaps your post match briefing glossed over the bad slightly, as I can't really think of any reason to be particularly disappointed with this report as written?
