Quick question really aimed at you DIR guys... I really like the concept of your brain being your primary SPG. I already kind of do this, meaning when I look at my guage I expect to see around a certain number. This basically comes from experience.
My question is since it is specifically taught to GUE divers how do you guys do it? Is it just experience or is there math involved? The only way I can think of is multiplying sac/rmv by ATA. I really don't want to do that underwater if I don't have to. How is it taught to you guys? I consider myself pretty good at mental math considering I have to do it for work but I'd rather not underwater if there is some rule of thumb etc.
Someone school me please and thanks!
