Roaky-
I'm a bit rusty at the calc part, havent done it for some time now (hardly dove in the last year).
Let's see. first of all I belive I said 50 meters, which is a bit les than 190'. Now- we didnt take the 1.4 limit, which is very conservative. We took the 1.8, which for relatively short, and without any serious phisycal work is conservative enough. based on that I belive we used 30% mixture for the dive, and 50% for the stops, as we didnt want to use 100% after the exposure of the dive itself.
