Is it too short on connect time 3hrs for 22hr international trip

This is a great article!  Thanks for sharing and put on top section.

Regarding to flight connect time - delay is normal, or on-time is precise.  For 22hrs international flight, for example, how can you book next flight in 3.5hr later?  While in US continental, in winter storm season, I don't see dare to book like this way.  Could you please advise how to deal with delay, flight miss, etc.?
