If an organiser sends in his results very promptly and if both validation sec and the recorder are sat waitng by their computers instead of out riding their bikes, and if the new automated ACP process works as intended for BRMs, then the whole thing could, in theory, be complete on the AUK website in about a week.
That's an awful lot of IFs though, and in reality I doubt you'll see many approach that sort of speed.
In previous PBP years a turnround of sub 24h has been achieved, for the final qualifiers. Though that was exceptional, 3-4 days has proved quite do-able provided of course that everyone involved is willing.
Change of topicI've seen this question asked a few times, and I can't remember where, so I'll answer it here -
it is now possible, if you log in to your 'my details' page on the AUK website, to
choose your ACP club allocation. Later in the season you'll find it becomes locked and inaccessible (like it was this year, this is because ACP likes it that way) so you have a couple of months to do this, that's all. You don't
have to do it, but the option is there.
