"The remainingMinutesInOven method should reuse the logic implemented in expectedMinutesInOven" should take into account fields of the class.

Hello there!
I got the recommendation I put into the title for this exercise. I think this recommendation seems to be wrong. The method remainingMinutesInOven() is a getter method, as it only returns a predefined value.
Do you really reuse getter methods in other class methods to use said value?
Storing the value in a field and using said field in other classes seems to be the more effecient way in my eyes and is thus a slightly misleading recommendation, I think.
