Oil checking

This oil checking, on my t/bird lt, in the manual it says, run for 5, stand for 3, check level. Now when she is cold, when we would most of us would check levels, she is way below the bottom mark, when run for 5 mins, she is above the top mark, not by much, i understand how fluid changes its profile when warm, but this seems to work in reverse. Some one put my mind at rest.
