Computing average access time is more complex when sectors are more densely packed on the platter's outer portions because the assumption that an average access requires moving the read/write head over half the tracks is no longer valid.

Quizplus · Accepted Answer

When sectors are more densely packed on the platter's outer portions, the read/write head needs to travel a different distance, making the assumption that an average access requires moving the read/write head over half the tracks invalid. This increases the complexity of computing the average access time.
