Also differing accuracy and multihit variables, which may have the same expected value but increase the variance, which means cases where the two don't line up perfectly are more common. Another factor is TP return after WS, which may place one job ahead of another. Disregarding even the fact that despite x-hit builds it may take people a different amount of time to get to the required TP. What if a SAM uses Meditate? What if Conserve TP kicks in, what if one job makes 50 TP after opening the SC before the other job can even go? And, probably the biggest factor, is that sometimes the best weapon skills don't close required Skillchains. Will you give up Ukko's Fury to close a Darkness Skillchain?
Also, keep in mind that his math was performed with jobs that get a Skillchain bonus.
Skillchains are not rewarding enough to be employed regularly. That's the only reason why people don't do it. Sometimes it actually is rewarding, and that's when people do use it (see my first example, KS99 turtle). But most of the time it's just not worth it, nowhere near it.
