Seems like a stretch to me. Is there anyone outside ET who even know who this is?
What do you mean ?
As for Jack known out of ET, I know he wrote on TradersLaboratory and one or two other websites. I remember among all I've read about, on and from Jack, that he said himself along years he participated to different threads on different websites. What surged and was said by all his followers and a majority of his destructors, was that he published and wrote the best, most refined and perfectionned method on ET, along the last years of his life.
As for 'proof', I have myself 'followed' someone who have not provided any and I have learned immensely from this guy. Not only that, but I have gone far beyond what he has supplied publicly since he merely started me upon a path which I have explored further with a line of questions which begets new questions.
But the difference between this guy and many others on this forum is that he hasn't made any claims and nor is he trying to teach anyone. He's merely laid out some concepts and ideas that a clever guy could further explore on his own.
Who's that ? I'm not sure to get the point you wanna come to.
Is it too much to ask for any links where I can find this? As far as I know there haven't been any, but it's quite possible I have simply missed it.
I remember 5 years ago, I read a post of Spyder, he had projected and extended his rtl's at the end of the day, into the blank right part of his chart. let's say, for the next day, for tomorrow. He had invented, created channels in-before, saying : if tomorrow volume did this ("this" meant in his post : at the point he had arbitrary fixed in the future), price would do that. Both volume and price actions were arbitrary anticipated. The goal of it, was to just adapt, adjust its drawings the next day, compared to what he had anticipated. Remember when Spyder said "whether this change in price will last long or not, I cannot tell in advance" ?. In this example he had posted an arbitrary bet on "let's say tomorrow volume will, here do this, and so there will be a change here, then another here, and a last one here". He was acting like he knew, in order to be able the next day to adjust from that hypothetic history.
Next day, chance, his drawings fitted at 90% with the history of the day.
Let me find the link of that post if it exist still, and I post it.
Another personal example I can give you : when I started with that stuff, I did not do it alone at the beginning. A friend of me was also involved, but we never concretely worked "together".
One day, he took a sheet of paper, a chart was impressed on it. He took another chart, a blank one. He drew by hand volume columns, repeating what had really happened on the chart. And not even a glimpse at price bars. Nothing.
He gave me the impressed chart, and asked me : what was the open of the first price bar ? its close ? its high ? its low ?
I answered him, and he began to draw price bars, in function of the volume bars he had copied.
5min later, he had created a story of price bars, corresponding to the deduction he could do from volume and his comprehension of JH method.
Believe it or not : the channels, ftt spaces, fbo space, all the drawings on price pane, was INSANELY close to reality. AND hold on for the best :
the open, close, high and low of the last price bar was ALMOST THE ABSOLUTE SAME to the last bar of the impressed chart I handled.
Life separated us, and I don't know about him since several years. Nonetheless, he was able to answer at any moment to : if volume does this, what must price do ? Although at that time, this mastering he had, did not lead him to master SCT and win €, he had an amazing ability to deduce price from volume. But as Jack used to say : quite perfect is not enough. In other words, although that capacity to understand the PVR is an absolute necessity, there's even more to get to reach money.
I assume, to quote you a bit

, do you know anyone out from ET and from Jack's followers, who could do so ?
