Not that it would have been sensible to plan on using those services
after a late evening event anyway.

Given that that is their explicit purpose that seems a silly statement,
though as with taking any last train or bus there is always a small risk of
getting stuck.

The services are simply not late enough to be able to make an exit from
the events and get to the stations in time. eg The late basketball
sessions don't even start until 22.15 and are scheduled to run up till
midnight. A last train at 00:30 is hopeless for that.
