We are not talking about theoretical safe lengths of runways for the safety and comfort of the flying public.
We are talking about how short a runway could be used to land or take off a 777. The big factor would be the pilots ability.
Some pilots would land or take off in a much shorter distance.
If you use a formula like you suggested, for a 777 the runway would probably be about 10,000 feet long. - tom
There was an oversized 747 that landed at the wrong airport in Kansas City last fall. They stripped it down, flew in some short takeoff experts and got it off the ground on a runway that IIRC was 1500-2000ft shorter than the ‘minimum’ recommended runway for that particular plane.
I’ll also note that the pilot on the Malaysian flight had his own 777 flight sim setup at home. Possibly to practice short takeoff and landings.

I was pointing to your statement that runway length is influenced by passenger comfort.
It is not.
As for your comments about what is possible.....
Certainly.
Hell, I knew a captain for Eastern that regularly landed a 737 and turned off at an intersection that was not easy to do in a Bonanza.
If he had lost an engine and had to blow and go, he would have created a news event and a huge mess.
Someone turned him in for it and he got a lengthy vacation with no pay.
Many years later he killed himself and the son of a friend of mine while demonstrating his superior ability.
And of course there are the real pros that they send in to fly big iron off of the 3500 ft. runways that the crew mistook for their destination.
But none of that has anything to do with passenger comfort.
