Buoyancy Calculator Spreadsheet?

[CaveSloth]

Anyone have a link to the latest and greatest spreadsheet for calculating one's buoyancy based on one's rig? I downloaded the Buoyancy Estimate Worksheet v3.xls file but this was not the one I remember seeing in the past. I remember a spreadsheet with a bunch of tabs where you input how many of which kind of tanks you had, how old / thick your wetsuit was, etc... and seemed a lot better than this one. It told you things like buoyancy at start and end of dive, mentioned being sure you could "swim up" certain weights that would change color when they got too high, took into account dive depths, etc... Does anyone know what I am talking about? This v3 one doesn't even have Faber LP-85 tanks listed and you have to manually enter your cylinder negative buoyancy rather than the spreadsheet calculating it for you.

I have version 4.4 that I got from the first sticky post in the advanced scuba discussion section. Check there.

Need to take into account the body. Fat is buoyant. Its density varies. I seem to recall that 10 extra pounds of low quality fat needs about a pound of lead but that could be off.

LOL, how about if the extra pounds are in "extra high quality fat", like undoubtedly is the case with me ?

Yep, that is the one. Up to v 5.7 now.

Article I saw gave a range of 0.85 to 0.9 or something like that. I took denser fat as better.
