I have thanks. If I try to understand your description your thinking that becuase we have twice the area of light he thinks you loose light whereas I assumed he means due to none perfect transmission trough the TC. I understand what your saying however.

Yes, it’s because of transmission — everything in the optical path absorbs some light regardless of how well it’s coated, its material, etc. Basic physics.
