I sized using the usual "big-big + 1 inch" method, and it was fine. Like previous comments mentioned, this might be best if you are exceeding the recommended cassette sizes.
A rider might never want to use the big-big, especially on a triple, but it's easy to lose track of the current gear, and shift to the big-big by accident.
totally get that in this case doing big big plus 2 links gave me a chain that jammed (yeah could be user error but I checked 3 times, marked the chain with a marker, etc) using the smalll small method above gave me a lot longer chain
