I've done 2 deco dives in a day more often than I've done just 1
My last deep dive workups were (all deco dives unless otherwise noted; all deco dives are on air as back/bottom mix with 50/100 stages for deco):
March
Day 1 - 43m (no deco)
Day 2 - 50m & 32m (no deco)
Day 3 - 50m & 55m
Day 4 - 65m & 70m
April
Day 1 - 46m
Day 2- 50m & 19m (no deco)
Day 3 - 55m & 23m (no deco)
Day 4 - 55m & 65m
Day 5 - 64m & 75m
July
Day 1 - 45m & 55m
Day 2 - 30m, 37m & 31m (all no deco)
Day 3 - 18m (no deco)
Day 4 - 33m (no deco) & 65m
Day 5 - 75m
Day 6 - 29m & 19m (no deco)
Day 7 - 85m (birthday dive!)
That's what's in my logbook anyway, the days might not be exactly right as I only filled it out later - but the order is right. SI between deco dives is usually 2-3 hours, with the runtime cut on decoplanner as a series of 2 dives (where applicable)
I dunno if I should put a disclaimer on this or not - people complain either way. Anyway, here it is: I suggest you don't do deco dives without proper training/mentoring/understanding/equipment
