The lowest UA credits (via ORD) is 2200 miles! IMO AC invents their numbers - the only place I know to check mileage totals is by calling the Elite line and asking - which is ridiculous!
AE miles are actually given on Statute Miles on a great circle route. The actual mileage from YYZ-SEA is 2052, so you received 2 extra AE miles. Your lucky day.

It will be close, but not exact.
