As long as i am bothered thats all that counts, it matters to me i worked for that result as did everyone else i am sure they would like to be correctly credited. Surprised you are advocating that people should be credited for times they did not achieve but i suppose thats a Wharfedaler for you.
Having relooked at the leader board the unofficial results, one of the names ahead of me and not in my group finished 20mins ahead which if i was him i would be a bit annoyed at being given a slower time. The other was 20 mins behind, if there is mathamatical explanation for this based on waiting times etc would be really interested to hear it.
