FWIW, here are a couple of dives (asuming you had enough gas to have that much bottom time). One with 40/85, one with 85/85. All depths are in meters. Since this is purely a recreational dive gone bad, back gas is your deco gas.I dive 45/85 and routinely dive small deco amount dives - something along the lines of allowing myself to get 10-15 minutes of deco (TTS 15min max). These are at rec depths with a source of some deco gas. My first stop has never been deeper than 20' per the computer.
With that being said and those type dive profiles - diving 85/85 or 45/85 is no different.
The dives I do are recreational dives, I'm right there with everyone else in the group other than I may stay a bit deeper longer than the others - it would be exactly like someone that accidently allowed themselves to slip past the NDL.
To me, this is not an insignificant difference
