I’m not sure about that, whereas there is better capacity on TPE now, the frequency is much less than pre-COVID, isn’t it only two fast trains an hour now? And due to the fact other services have just been removed from the timetable, I bet they aren’t evenly spread. This is all before you factor in all the cancellations, where you sometimes end up with two cancelled in succession and gaps of 90 mins and of course the endless industrial action
