exactly. the front rows (in fact i *think* all the rows) are determined by that ‘previous results’ bit in the entry form.
See, they say that, but in reality it’s not.
Last year (my first Mega) I was a third row quali starter, despite me putting down nothing in the box apart from my race number. I qualified 18th in my heat & was about 220th in the main race.
This year I filled it out, national ranking, previous Mega quali result, key race results (DH wins & podiums) yet I was nearly 40 places down on 2011. There were people on the front row I know (and race against who I have regulary beaten).
I think, other than the top 5, or maybe 10 – it’s pot luck where you end up. One guy in my quali I know from racing Nationals, he entered the day it went live, is a Senior who consistently podiums at Nationals for the last few years, and came in the top 50 of the main Mega race last year – he was on the last row of our quali.
