The only things? Really? So when we get an ECAM/equivalent at V1 - 20kts you've got all the time in the world to assess, analyze and make a critical decision do you? Personally, if I'm sitting in the hold over my recently closed destination on min fuel looking for alternates, maybe with weather, I'm happier sitting next to someone who can quickly do the math, rather than old mate who wants to sit on his hands because a bit of time pressure buckles his/her/its ability to do the 3 times tables.
Perhaps having the intuition to not end up in such a situation in the first place is a better option.
