Simple: dive tables
30 min for the first dive.Secure round-up in dive table is 35min with a decompression schedule of 10 min at 10 feet.
RDG for 80 feet 35 min is: G.
Surface interval:
RDG = G and surface interval is 1:30. The result is class V.
Nitrogen penalty times:
second dive at 70 feet and class V:
nitro penalty time = 18
no decompression limit = 17
return to table 1:
30 min + 18 min = 48 => 50
70 feet at 50 min => 10 min decompression stop at 10 feets.
The second dive is not necesarely deeper, it's just 'longer', in the point of view of nitrogen penalty.
RMK: I'm running a canadian table from ACUC.
