I already commented about SAC rates in an earlier post when I considered 1 cfm pessimistic, but based on the even more pessimistic scenario you just presented with not just one but 2 divers somehow managing to consume 35psi normally and 105psi under stress (!!!!), this buddy pair should not even be thinking about planning a dive to 130' on an AL80 until they get a lot fitter and a lot more comfortable in the water.
In fact they really need to find another more relaxing hobby.
Fitness is only one factor in air consumption. Stress is the real concern. As someone who built gas management exercises into my AOW curriculum, I've seen divers ... especially newer ones who are still working out their technique ... quadruple their "norrmal" consumption rates once they were stressed.
Furthermore, to "assume" that someone who's stressed out and relatively unskilled is going to make a routine ascent, following recommended ascent rates, isn't realistic ... that only ever really happens on the Internet. In real life, it may take them a while just to get squared away enough to begin an ascent ... particularly if the problem involves something confusing, like a free-flow that is going to have them attempting a valve shutdown just so they can manage to see each other through the air bubbles.
A direct ascent from 130 feet ... if it's done safely ... will take several minutes (exact minutes will depend on which agency standard you are TRYING to follow) ... and if it's not something you're used to doing, expect a bit of acceleration, deceleration, possibly even sinking a bit as you try to slow yourself down ... ESPECIALLY if you're attempting it while clutching your dive buddy's BCD strap in your right hand.
It's not the "simple" process that most people imagine ... particularly if you've never tried it before. Add in some additional factors like cold water, poor vis, unfamiliar equipment ... things that typical recreational divers the world over have to face from time to time ... and you've got a much more complicated scenario than the textbook claims you should have.
Which is why you want to leave adequate reserves to deal with these problems ... because until you're actually faced with them you have no way of knowing how you're going to respond ... and for damn sure you don't want to find out halfway to the surface that you got it wrong ...
