I believe the real question should be why is it so low?
From a business point of view it makes absolutely no sense to grant AC status to someone who may potentially do as little as 5%-10% of their flying with AC.
And while 10,000 / 5 segments is IMHO acceptable for 25k status, when you are looking at 100K status I feel it should be more in the range of 40,000 / 40 segments.
