Good. Let me continue to help you walk through this... and we will even assume the metering logic to be identical (based on a light meter) and the scene of course:

You have 35mm f/4 lens on APS-C and 50mm f/4 lens on FF. Now, what do you expect the shutter speeds to be?

Let me direct you to this post upthread:

which answers all that, and is followed by a miserable and utter comprehension fail on your part.

No, it resumes the Great Bustard run around (in circles). The question is simple enough, and shouldn't take much more than a sentence. Heck, I will make it even simpler for you to answer with a yes, or a no:

35mm f/4 on APS-C for a scene versus 50mm f/4 lens on FF for the scene, do you expect shutter speed to be about twice as fast for the FF?
