SAC rates in imperial

[waterV]

Hi,
I am using a Vyper so I do not have air integration. I have entered the tanks I use: 100cu ft (about 12.2l) and a 119cf ( about 14.8l). When I enter the psi I used, I get SAC rates in the 0.06 to 0.09 which is about 10 times lower than "normal". In metric however, it seems to be on the spot with SAC rates from 15 to 22.
Am I doing something wrong? Thanks!

BTW: LOVE the new version I just started using

Maybe your working pressure is wrong, or the depth/duration/air usage. SAC rate is covered here:

I am using steel hp tanks. Their working pressure is 3442 psi and this is exactly what I entered. The depth and duration are recorded automatically by my computer and they are coherent with the dives I do. The only other information I provide is the air used. For example:
a dive for 53 mins at a maximum depth of 28ft and an average depth of 22ft, I used 1700 psi of my hp100 which was filled at 3200psi gives me an SAC rate of 0,07

In metric, the same dive, 53mins at 8.53m max and average 6.71m, I used 117 psi and I have an SAC rate of 16.14

The only thing I changed was the display preferences... Anyone else having this behavior in imperial?

Thanks!

Please email me your MacDive.sqlite data file and I will take a look at your numbers.

Thanks for the email. You have some data wrong with your tanks, I've emailed you with the solution.
