I mentalize both systems. Any difficulty is worth it since it has compatibility in mind. It’s the one I use in groups I administer because of this. Doing things the normal way, for a lack of better words, seems and even feels outdatedly/unthinkingly convoluted and skewed, as someone coming from several different backgrounds. The former is also less of a strain (both mentally/technologically) once one becomes accustomed, to put it one way it’s like the Lojban of timekeeping.
