Stage braking requires some self control to resist the urge in a panic situation to just 'grab a handful' of the brake lever in one action squeeze the dear life out of it. This creates a shock to the whole bike's composure and could send you straight into skidding or a stoppie. Neither of which will do stuff all to reduce your speed. Certainly when leaned or wet it will dump you.
The better way is to;
first apply a gentle squeeze- just enough to smoothly transfer the bike + rider weight towards the front wheel and to firm up the forks, which will in turn press down on the front tyre and increase the size of the contact patch. This is just for 1.0 to 1.5 seconds (depends on how little time you have before impact!
Second stage is increase pressure on the lever i.e. squeeze harder - but still not maximum force if you can resist the urge. Now the front tyre really starts to GRIP, very important that, and what you really need instead of skidding.
Third stage - full tit squeeze on the lever. , a second or two later and you can now go for broke and squeeze the hell on the lever. By now the tyre has reached it's maximum ability to GRIP, the bike has some degree of composure. This is what ABS does but by giving the lever progressive steps you help the ABS do it's job even better.
When I first experimented doing stoppies this is just what you needed. Get the forks compressed into a 'stiffy' and the front tyre spread for maximum grip before the big squeeze.
Another way to explain it would be if your measured how much effort you applied when squeezing the brake lever at 1 for the lightest of touches and 10 absolute hard as possible. Then you would squeeze lever a second each at say 3, then 6 then 10.
I like your description. The thing I will pick up on is "depends on how little time you have before impact" I defy anyone with half a brain cell to explain to me after thinking about this that its smart, acceptable, good riding technique or even remotely not idiocy to ride so close to the arse of the vehicle in front of you you can read their WOF sticker. I see this happening EVERY SINGLE DAY. People on bikes paying absolutely no regard to how close they are to the vehicle in front or how long it will take them to react never mind begin braking effectively.
As I said, I like your description and is a terrific skill to work on and to practice so you can retain it. However, without giving yourself time to use the technique its all academic really. First and foremost (for me anyway) is good forward observation, that will give you space and time to call on all your other skills. What you talked about uses up well over 2 seconds once you include a response time. Too short a following distance simply does not allow that amount of time.
Life is not measured by how many breaths you take, but how many times you have your breath taken away
