However, it still seems that the calendar this year is 1 week back?
Usually RG wraps up by the first weekend of June?[/QUOTE]
I don't think so - RG is always the last week in May/first week in June with Wimby being last week in June/first week in July. USO is last week in August/1st week in September, AO is last 2 weeks in January.
These are the 'anchor points' for the entire calendar. 250s/500s/MS1000s might move around to accomodate Olympic years but the slams don't move. It's been that way for some time now.
