Honestly you'd probably have to check with QB support to get a definitive answer on how they construct their poll. The Google Sheets API returns a row and column count so if you delete and then re-add a row where the row count doesn't change I suppose it's possible that if the Poll is checking that it wouldn't register. Looking through the api docs I don't see a date modified but I merely skimmed so it's not entirely clear how QB is determining if it changed unfortunately.
Interesting. Thanks for doing this research Chayce!
