While I enjoy upsets, I would be in favour of re-doing the matches, in order that the "lifelike" nature of the competition is maintained.
It seems rather unfair that major contenders should go out as a result of the shortening of the matches, particularly if you are to revert to the original format for the remainder of the second round matches.
Although it would, of course, give the Barrow-Downs team an advantage ...
