I meant, 2 different people on different reservations.
If you are waiting for U space, and I am waiting for U space, and only 1 seat is ever released then only one of us is getting a seat, regardless if how good the alerting system is. It's not a latency issue, it's a supply and demand issue.
Having a lower latency system just makes it more likely that the other guy gets screwed instead of you. Which is fine
