I think 100 is a better default choice. This will allow a vast majority of customers to complete in less than an hour with risking too much contention. Even if the upgrade were to take 2.5 hours, it doesn't matter. 100 is a lower risk number. Perhaps overly conservative, but there is no need to take unnecessary risk when it yields no real benefit. The user can still throttle it up if they want more TPS.
