130bar for 2x12s gives a gas used of 3,120Lt therefore 23.28Lt/min, not the 21.7Lt/min Subsurface displayed.
If you’re constantly changing your configuration you’re not giving yourself the chance of becoming familiar, and comfortable, with one setup.

Which becomes even worse if we calculate the average deep manually, being (21+1)/2 = 11 meters rather than 13.1.... making the SAC even higher.You are totally right: 130×24÷2,31÷58 = 23,2870577698 litres/minute
So....
1) How the heck is Subsurface calculating the SAC?
2) well... that makes things a little worse
That is not likely to be your average depth but rather the average of your deepest and your shallowest depth. I am assuming 21m is your max depth, and 1m is the shallowest you can measure.Which becomes even worse if we calculate the average deep manually, being (21+1)/2 = 11 meters rather than 13.1.... making the SAC even higher.
