I struggle to believe that the rear brake does nothing 
If the rear tyre is in contact with the ground with a braking force applied I can’t see how it isn’t contributing to stopping distance?
Very interested by the statement “you will stop as quick if not quicker with just the front brake”
FFS I’m going to go and spend actual time testing this now 
Sheldon Brown has settled this one already:
The fastest that you can stop any bike of normal wheelbase is to apply the front brake so hard that the rear wheel is just about to lift off the ground. In this situation, the rear wheel cannot contribute to stopping power, since it has no traction.
You don’t believe you can endo if you’re going 30mph and lock up the front brake? That was what I said way back in the beginning with the “breaking” 
What? No. I’m saying I’ve never made a front wheel skid on dry pavement.
I was just thinking about Sheldon today. Never met him, but sure miss his wisdom.
“On good, dry pavement, unless leaning in a turn, it is impossible to skid the front wheel by braking”
I’m happy being on the side of Sheldon Brown on this 
RIP
Well, I have front wheel skidded a handful of times, upright on “good pavement” so despite how good Sheldon was, he is not infallible. Considering the tiny contact patch it’s totally reasonable to experience when things go right (or wrong).
I can confirm by the skid marks I left on the sidewalk in front of the house as a kid that the rear break does indeed help you stop. 
Your pavement was clearly not good enough for Sheldon! :-p
Sheldon was a true expert when it came to the technical and mechanical aspects of bikes…that doesn’t necessarily make him an expert on all things bike related. That said…
Which is why we are talking about shifting weight backwards when braking to counterbalance this effect.
You beat me to it! I seem to have missed a lot in the discussion….but but not this

Bicycle quarterly also confirmed it in actual tests on actual bikes. No link as it was in the periodical (sorry)

This, like some other related discussions about the ideal vs the real are funny to me at times. Sure, in nearly scientifically sterile situations and environments, those things (front only with rear lift = best) are true.
But once we get beyond these controlled tests and into the countless variables outside (mixed road surface texture, cleanliness, crown, wind, humidity, moisture) and the lovely nature of riding in groups… the reality is that mixed brake application is likely best.
I get it and understand the “perfect” solution here, but in my 3 decades of riding and racing just about every bike genre there is, a decent mix of brake use tends to rule the day. Exceptions surely exist when we add in loose surfaces, non-straight braking and other stuff, so I will again mention that reality includes more nuance than many of these 1-sentence summaries can properly address.
Well, I think this discussion was pretty clear that it was not pertaining to real world stopping. I go years without having a need for a “max stopping power event.”
This is all not particularly applicable to everyday riding of course.
We are one step away from somebody quoting that lunatic Grant Peterson
I honestly have never given this much thought in the 14 years I’ve been riding/racing. I just pull the brakes and I stop lol.
how? He is a researcher who hasn’t made any incredible breakthroughs altho I do follow his training philosophy.
electrolyte drink mixes are not worth it. The only electrolyte you need to replace during exercise is sodium.
High carb drink mixes are incredibly overpriced and the science isn’t settled on glucose:fructose ratio.
This is just true.
