If I do friendlies I've long since stopped looking at the score. I'm only interested in the flow of the game (in as much as I can tell). Limited value admittedly.
I had one friend who was having difficulties a long time ago and although he was a much higher level, repeated friendlies were useful to try to get things working right. Score didn't matter and was sometimes 9-0 or 2-1 (but I always lost) but he did get a new way of playing working. PS. I could get lots of shots and attacks but ultimately we were repelled.
