I may be wrong, but so far as I can tell only wins and losses are recorded. I was thinking that it would be fun to have an average points scored / game played rating. Also, have a survival rating, namely the % of games that ended without you having been shot down.
It just seems to me that when you do well but come 2nd etc, there is nowhere that it is recorded, you just get a loss. At least with average points you would get something out of it rather than a big fat addition in your loss column.
Out of interest, I just achieved my first victory in BM! I am slowly getting the hang of it, though the victory was more to do with lucky dice rolling and chit pulling than flying expertise!

Gratz on your win Ionwerth.
