I've just started working with this spreadsheet (as found in post #82,
The "Ultimate" wing lift calculator :)) and I have some questions.
- What are cells C3, E3, G3, and K3 for? They say "Catalina 80", "Gas?", "BC?", and "Suit?". I think they are just there for me to enter the specifics of my setup into, so I can save off different setups and refer back to them easily. But, in that case, what is "Gas?" for? Do I enter something like Air or EAN32 or something? Why? What difference does that make to the context of this spreadsheet?
- The sheet appears to calculate based on a max planned depth of 66 feet. And if I want to change that, I have to unprotect the sheet and then change the formula in cell E38 to multiply by something other than 0.33. Is that correct, or is there some other way to change the max depth calculation?
- I'm okay with assuming 50%, 33%, 25% for 10m, 20m, 30m. Any suggestion on a factor to use for 40m? 20%?
- The result table has columns for depth1 and depth2. I have inferred that those are the values for initial arrival at planned depth (i.e. 66 feet) and at the end of the dive, at the same depth, when starting to ascend. Correct?
