What is your formula for calculating Liters/min?
For my dive of: 29 min, 75 bar used, avg depth of 8.56m, using a 12L tank (working pressure of 224, though not sure what that is used for)
Your calculator says I breathed 0.073 L/min, I calculate it as 16.72 L/min.
My formula: Used (bar) Tank Size (L) / Time (min) / Avg Pressure (bar) {avg pressure = avg depth / 10 + 1
75 bar 12 L / 29 min / (8.56/10 + 1) = 16.7212 L/min
You should allow decimals in the avg depth too.
