Sorry, my friend.
I know about that, Kunrei is pretty good too (and alike too).
It makes sense for me because I use it.
I wait for a direct, correct and useful clue about romanization of interjections using modified Hepburn because I must to be coherent with my previous translations (all under modified Hepburn [revised Hepburn-second variant] rules).
Anyway, thank you very much for your participation.
