Lots of duplicates, get them sorted out
To address some of the comments:
Yes, the formatting isn't quite right. But the spreadsheet gave me serious headaches when I tried to use either two decimal places or two colons in one field. So that's why it is the way it is.
In hindsight it would've been better to get the two-colon format working, because there has been confusion with the h:mm.ss format and people choosing 66 seconds or whatever. I'm not sure what to do with the ones which have a post-decimal number over 59. I'll accept PMs from the people who have guessed those numbers if they want to update them, otherwise I might just round them up to get them in the right format.
