Hmm, how much time would he need to do the 4x4?
Note: the time limit for how long competitors have when excused for other events is not a hardwired number. It is determined by the games committee (rule 7-3-7). They could allow a very long time. And in the case of a competitor that has won the event, the only harm for an excessive delay is the official running the event may not want to wait. (With one competitor left, you could release everyone else.) I find it hard to believe that once he is the sole competitor left that they would deny him the opportunity to set a record.
Anyway, some suggestions to try to let him have his cake and eat it too:
- Running the first leg of 4x4 would save him some checkout time (~2.5 minutes, or 1.6 mins if he is 2nd leg).
- Make this group of 4 the "B" team with a high seed mark so they end up in the first heat. This way he isn't trapped over at the starting line watching other heats run.
- Volunteer to officiate the PV event and drag it out or speed it up as needed.
(And if you are the one timing his absence time, ...)
