In gen 1 and 2, text generally prints in batches of 3 characters every 3 frames, you can call this text frame rule. Clearing text at different times can affect which cycle of 3 characters will play, this makes it identifiable if you cleared a textbox 1 or 2 frames late (clearing 3 frames late should realign).
Spaces and punctuation count as a character, generally the end of a line does not have a space though.

This document lists a few Red manips, if your text did not print this way it means you failed a textbox.
