TBH the best corn on the cob I’ve had the pleasure to encounter was fire grilled {in husk, resheathed after silk removed}, but the standard I’ve known for home grown sweetcorn is ~90s in low boiling water. Any longer makes it dull and unnecessarily mushy.
Corn needs 1m in boiling water. Not 20.
I don’t think it needs a whole meter… Maybe 10cm of water at most
