Wow!
With all due respect, I don't know how you came to be
Old Smokey, but I think your dissertation is a little off the mark.
I suggest you read some performance books, especially Boeing's Takeoff Safety Training Aid, IMMEDIATELY.
Empty Cruise
"...but what of wet or contaminated runways where the screen height is 15 ft, not 35??? "
Where in Gawd's name did you get that from?

Do I understand you to mean that you are reading and ASI approaching V1 rather than looking outside???
It is recommended by Boeing (and other manufacturers) that the V1 callout be made 3-5 knots prior to the actual V1 so that the spoken word is complete and registers by V1. That does not mean V1 Decisions are replaced by deciding to STOP before V1 unless, of course, circumstances dictate otherwise. It's obvious and confirmed by the variety of opinions on this topic that performance remains the least understood by pilots.
