Am I missing something or is this a glitch?
Those are the correct mileage requirements for those sectors. IAH/SEZ when upgraded as a ‘through’ upgrade would be 106470 but the sum of upgrades for the individual sectors is as above. When you use auto upgrade (which is unreliable), you can only do this sector by sector. The best way is to just set alerts and in addition check regularly on MMB if upgrades become available. In the - somewhat unlikely - case that two sectors become available at the same time, you can upgrade them together and get the lower rate.
