The formula makes sense to me so no issues there. Curious about its usage. I know EAD is handy if you're diving EAN and using dive tables.
But do people also use EAD for nitrogen narcosis management? If from a nitrogen narcosis standpoint I'm comfortable diving air to 100', I'd have the same PN2 diving EAN 30 to 120' while not exceeding the mix's MOD (assuming a PO2 no greater than 1.4).
Makes intuitive sense to me but I know there could be other factors - narcotic effects of oxygen, etc. With trimix I know there's a formula for Equivalent Narcotic Depth which does treat O2 as being equally narcotic as N2 for safety reasons. Beyond that I haven't dug too much into END as I'm not diving trimix.
