In reply to alx:
The four minute rule did produce one exciting moment when one of the girls topped with a second or two on the clock. However, I'm sort of expecting more last second heartbreakers than sends. I'd prefer 4+ to give time for three good tries but I guess once the setting difficulty and style adjusts itself to the new realities of what's possible in 4min, I guess it'll probably be sort of ok(ish).
