I think that the questions about when you usually update to a LTS or non-LTS release are important and relevant, but that they also miss an important aspect: why people wait as long as they do (or do not wait).

Thanks, that is good feedback. I’ll add this (along with the earlier feedback) to the notes we have so that when we run the version survey again, we can get more information.
