[RM2K3] IN 'MESSAGE' DIALOGUES, HOW MANY CHARACTERS ARE PRINTED PER FRAME AT VARIOUS SPEEDS?

Does anyone know? When a 'Message' command is printing dialogue text onscreen, how many characters does it print per frame at text speeds 1 and 2 in RM2k3?

EDIT: Nevermind. I think I figured it out. The answer appears to be 4 and 1, respectively.
