The list looks correct to me, but I believe there is another tie breaker in here too. Supposidely the method of payment for the upgrade also affects who gets the upgrade. If you are paying with "miles" you trump the 500 mile certs. I believe Miles also trumps SWU, which trump the 500 mile certs. In other words, a 1K on a M fare using miles should trump a 1K on a M fare using a SWU, or 500 mile certs. Now this may already show up in the placement on the DM list. However, numerous UA folks have told me that the best way to ensure the upgrade chances is to use miles. Now of course I could be totally wrong.
