And if not, isn't the general flash/red flash definition not also fundamentally flawed as it can't take into account physical screen size / viewing distance / etc, regardless of the existence of a "tool"?

Hi Patrick

I said that it DID have the same problems — and worse.    
But there was a tool that did the measurement automatically — so no one had to figure out the bits.

And I suggested you might look at that approach here too.   And gave other advice that related to the flash work.   Read my comments again.  Maybe I didnt write them clearly enough.
