With the BS-AC 88 tables (British Sub-Aqua Club), you do all your stops
at 6m and 9m.  Ascent rate is 15m per minute to 6m (or 9m if it's a 9m
stop), then 6m per minute to the surface. I always do a minute stop at
6m, as 6m/min is very slow, (ie one whole minute to go up 6m!) and the
thinking is that if you do a minute at 6m, then it helps if your final
ascent rate is a tad faster than 6m/minute.

I've been on sea dives when theres been a bit of a swell running, and
noticed that sometimes (when a big trough passes over, I guess) my
computer (a Monitor II) would beep and display the fast ascent
warning!
