IF the engine ran, the compute decides you have to wait xx time before you can have a reliable reading.
The warmer the engine is, the less time because the computer assumes cold engine oil takes longer to drain to the sump.
It does make sense if you think about it, and most people never gave that much tought back in the old dip stick days.. They would just shut down the engine, and check the dipstick right away.
So the dipstick could in those cases ,show a slightly lower reading.
