Once again, junior, you have demonstrated your lack of understanding and application of the regulations.

"HOW" a pilot determines the flight visibility is only tangentially related. However, the "HOW" is mostly irrelevant, because the FAA cares not HOW you determine it. If you count it in furlongs, parsecs, or statute miles, it does not matter.

The regulation simply states you must not have less than the charted visibility.

It is a binary. 0/1. You either have it, or you don't.

However, you are deflecting from the scope of your original claim - you claimed one did not have to determine it, or, that seeing runway environment items automatically suffices as "flight visibility."

It matters not the "how."

What matters is - it is REQUIRED.

End of discussion John.
