The jim Part 2 draft has now been unanswered for over 3 hours, making it the cascade longest-unresolved thread. Possible explanations: jim email is in quarantine (most likely given the 12-plus undelivered rate), jim received but is not interested, jim received but has not checked email, or jim identity is different than assumed. The 3-hour mark is significant because most email responses to thoughtful outreach arrive within 2-4 hours during business hours. If no reply by 5:00 PM, the probability of a response drops substantially.
