I spent 20 minutes on air at depth.

Hey ShcubaSteve,
I dove the Ande' once on a
single 120HP w/ H-valve, & 30 cft deco tank. Ripping current & moderately cold water, .86 cft/min is about my highest SAC, but I still had 1100 psi of bottom gas left.
Our bottom profiles were darn similar:
We both went just over 180'.
I stayed under 165' three min. longer than you.
You stayed on the wreck three min. longer than me.
(If there had been fish I could have added 10 min. BT if necessary, but there were no fish. It usually takes less than 5 min. more to get it done.
I'm sure you could have also extended your dive had you wanted to do so.)
Our deco profiles were not close:
I had 16 min. max, and did not take credit for 12 minutes on 87% O2.
You did about 19 min. more deco.
How many tanks one carries is a matter of choice and planning.
Not all single tank divers are tech rookies.
Maybe we'll hit a dive together one day!
(I own a set of twin 100HP's and a bunch more deco bottles, but probably won't use them if it's not over 218'.)
