If we report T/2, the sites which run a faster re-schedule will get the 'first' jobs. I suspect the smaller sites would tend to be favoured under these conditions. We could also agree on a global minimum wait time to return, for example 120 seconds. This would be the minimum returned. It would probably be less false than 0 seconds and give all sites an equal chance of running the 'first' job when there is nothing in the queue.
