You could ask for clarification from Oxford Uni / CTT? Could just be an admin/timekeeper error? My Garmin time was about 10 seconds faster than the official time on Saturday so could be worth a shout?
Will just wait for official results.
I'm not worried about my time. Just didn't know how a tied time works for pacings. I presume official results will reflect what's tester said.
4th get's BUCS points. 5th doesn't.
