zygote:
Not quite sure how you figure that. Surely if more people have 4 days off there is more scope for more attendance during those 4 days.
Don't forget the new 'rolling 8 hour' AAVA where you can volunteer for any period of 8 hours during the day to suit you or the ORO.
By the way, I hope that NONE of the people who voted NO to the early start are volunteering for AAVAs. If you don't want to get up 30mins earlier, why should you want to come in for any more days than you have to??? Of course... £500+...
