Thanks, I wasn't aware of that precedent, nor do I recall details of the stage (and I'm seriously impressed that you can recall in that quickly).
The rule (2.6.015)
Does not allow for some stages to be an exception, but of course what is in the rule book and what the UCI allow, even though the rules do not give permission for exemptions, are only vaguely related, so it wouldn't be a total surprise if they cover their backs by omitting Stage one, regardless of the rules of the sport.
But this cumulative total is a daft and innocuous method. When riders are not riding for position, their position should not be a factor, especially as the stage that will usually contain the biggest placing differences between GC rivals is likely to be the one in which they are least invested. The whole idea of giving the peloton the same time in a bunch finish os to avoid everyone feeling they have an abligation to be near the front for safety's sake.
Would it not be more sensible to have a countback weighted towards their best stage positions? GB has 1st, 3rd, 17th, 30th, 59th; ELB has 1st, 3rd, 5th, 52nd and 73rd. Their best two positions are equal, so look at their 3rd best: Longo Borgini would be the leader, and Brown would know that she needs 4th tomorrow (but 5th would do if ELB outside the top 17) to win. Reward them according to the stages when they made an effort, not the ones where the whole spirit of the sport is that they ride in in a non-competitive manner.
But maybe that needs a different thread, rather than further diverting this specific race's chat.
