Another factor to consider when asking whether ‘salt reduces cooking time’: Presumably, if the boiling temperature is higher, there will be some extra amount of time needed to raise the water temp that much. So your 2.6 seconds becomes (2.6s—extraPreBoilingTime). It’s feasible even that this turns your value negative. That, combined with the amount of time needed to grab the salt, and clean up any spilled salt (lets say 1 in 5 times) almost certainly ends up with you losing time, on average.
So your friend isn’t even technically correct. Bob is wrong on both counts.
I’d advise dumping him as a friend. Save your starchy water though.
