Say you're a former 135 guy that has 1,000 hours of 135 time that qualifies for an upgrade here. You've just got hired into your first 121 gig and get displaced to the CA seat with only a couple of months of 121 experience under your belt and are expected to be a CA.

Say you've got 1,000 hours of 121 time but you're still simply not ready to take on the responsibility just yet.
