💡 Rough baselines — reading: Chinese slow 350 / average 400 / fast 450 chars/min; English slow 200 / average 225 / fast 250 wpm. Mixed text is counted separately, then added. Speaking mode uses conversational pace (Chinese 250 chars/min, English 130 wpm) — good for sizing presentations and video voiceovers; real delivery runs longer with pauses and interaction.
