Hi DIR guys, i normaly dive with a CCR Rebreather and use a Shearwater Pursuit diving computer or, and a VR3 but would have some help on Ratio Decompressing used by DIR.
Example:
48 Meter 30 Min BT
DECO Min (= BT + 5 Min (as 48= 45 Mt. +3) = Totale Deco 30+5 = 35 Min

80% first Deepstop = ATA 5,8/10 = 0,58x2= 1,16 5,8-1,20 = 4,6 ATA=36M

Deep Time Mix.
48 30 18/45
36 Mt. Deep 1 min
33 Mt. Deep 1 min
30 Mt. Deep 1 min
27 Mt. Deep 1 min
24 Mt. Deep 1 min

18 Min (50% 21-9 Meter)

21 Mt. Deco 3 min on 50/25
18 Mt. Deco 3 min
15 Mt. Deco 4 min
12 Mt. Deco 4 min
9 Mt. Deco 4 min

6 Mt. Deco 18 min on Oxygen

Would that be the decompression You use? Or are there errors in my interpretation?
Thanks a lot
and save diving on Your twinsets
