If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

What did you expect the invitation’s time statement to include?
Where did you pause, if anywhere, during this attempt?
Which prompt required additional thought or information?
What wording would describe the effort without promising your exact completion time?

Author notes / illustrative keys where applicable:
1. Test whether elapsed time and expected effort are confused.
2. Record an interruption only if the volunteer chooses to explain it.
3. Identify content-driven effort separately from a pause.
4. Improve a qualified invitation without inventing a universal duration.
