probably politics.
as with the case in sispec, when i pretty much aced every
test(written and pract, like ippt gold & ex.wanderer) but
didn't even get a bloody #@!#@! platoon best. the fucker who got
platoon best pretty much got it because he was 'outstanding' in the
sense that he wore a turban. as in seriously... coz' all the
instructors knew him and liked to tease him about it. grr...! the
guy who got company best was simply, well, well liked by the WO
& instructors coz' he's always so bloody loud and hated by
everybody else coz' we know he really dosen't do squat.
or like smi, where i pretty much khenged everything and still ended
up with best team... my theory was that i did reasonably well, and
more importantly was laying low enough to not get marked by the
people in smi.
sounds silly but sometimes it's like playing a popularity game.
dunno if that's the case for ocs though... hmm.... 
but yah,
it continued all the way to &through unit life for me as
well...
