Agreed that the day of the week has an impact. However, from September to Christmas Thur, Fri, Sat, Sun, were not good. Prior to September the upgrades from SFo-PVG-SFO were better, but not now. It does not matter who has 100% upgrade record for 2010 on this route. The fact is if you have an upgradable Y fare now and want to use a SWU you have a 35% chance of clearing the one direct flight per day.
