Review readability and timing metrics together so you can identify cues that are too fast, too long, crowded or overlapping.

Readability is more than one number

CPS and WPM help identify fast cues, while line length, duration, gaps and overlaps show different readability or timing problems.

Thresholds are adjustable

The defaults are practical starting points. Set limits that match your language, audience and delivery requirements instead of treating one profile as a universal rule.
