Those percentages are such nonsense. They're totally ignorant of probabilities. I've been blocked by some of those accounts on twitter for pointing it out. They change drastically on one result which means they have created a probability on some assumptions but if they are wrong in their assumption, the entire probability % changes. The likelihood of the assumption being wrong should be factored into the percentage, rather than if arsenal win then the percent we quoted is accurate. If they don't win, essentially we have to completely recalculate the probability because the previous probability assumed they would win and made no allowance for the possibility that they wouldn't. It's nonsense pseudostats
