Why is ~1 suggested edit waiting for review?

Question

Today I noticed this:

Why does it say ~1 and not 1 suggested edit pending approval?

Answer 1

Most likely, due to the #s being cached, so they didn't want to pretend to be exact ("~" means "approximately").

As a matter of fact, half the time the # I see is actually wrong compared to review counts I see in the actual queues.
