Step, the way you worded your question about comparisons and what dive times can you get in these parameters, to be honest would take hours and many tables. If you could shorten your depth variation a bit, it would help. 30-50m 1-2deco gases 21-30% back gas is just too many variable to ask someone to generate tables for you. Never mind what level of conservatism you want.

Here is a basic idea using air as back gas and 100% deco on a VPM-B algorithm +3 conservatism:

Dive to 35m - 15min Bottom Time

Using Air & 50% - 5.5mins deco plus ascent time
Using Air & 100% - 5.5mins deco plus ascent time
Using Air only - 18.5mins plus ascent time
