Isaksson seems to be the origin of this technique, or the first one to be caught on film doing it. Watch that 18' + jump of his outdoors -- it is pure and the most beautiful example of pole vault technique ever captured in my opinion.

... I know him well and can confirm that almost everything in your analysis has been correct with the exception of his 100 m best which was 11,2 in 1974. However, he was very quick in his movements and therefore looked faster than he actually was.
Despite that I think he was as fast as anybody in the last 10 meters and he was in a better position at take off than anybody else. I know that there has been made a lot of speed measurements done and I think that I still can get hold of them. If I do, I will share them with you.
He was running high, with high pole carry, somewhat square to the runway. Maybe more important was that he tried to make an early and very high plant with the pole parallel to the runway at the moment when his right hand was at the level of the ear. The drop of the pole tip into the box could then be made weightless (right hand up and the left kept in a high position not allowed to drop) which made it possible to maintain speed better.
Other critical elements were that the left arm should be more or less absolutely straight and the right hand in front of the ear when taking the last step, the pole still somewhat square to the runway (what I mean is when planting the pole). He was also very concerned about the body posture (which seems to be an underrated element) and it is now afterwards easy to see how his straight left arm in the plant in combination with the body posture more or less forced him into an optimum point at take off and created the prerequisites for an efficient swing.
His grip varied between 450 and 460. The only time I have heard him talk about a higher grip was when he made 572 in practice with a borrowed pole (in El Paso, high altitude and a strong tailwind of certainly 5-6 m/sek according to his own info). That means he jumped at best 120 cm above his grip at a time when the standards could only be put 60 cm away from the box and that days vaulters did not even use that but I would say had them 30 – 50 cm away so you had to go very straight up to be able to achieve that. As I remember it, he has made even more than 120 cm but I will check that when I meet him next time.
On the Swedish TV they had a program a few years ago where they showed when he jumped WR 5.55 under very bad circumstances. To me it was the most optimized vault I have ever seen and I could not get rid of the impression for several days. Absolutely astonishing even if I have seen all world class vaulters thereafter.
The Swedish national coach at that time was Knut Pihl a good international class steel pole vaulter in his younger days and a mechanical engineer to profession. When I look at his paper on pole vault technique from that time and recall our discussions a decade thereafter I think it is fair to say that he is the original Petrov. It was certainly a combination of his interpretation of Kjell’s vaulting and his own experience and engineering skill that caused him to be very precise when he documented his theories about what today is modern vaulting. He definitively had control over angles and forces, weight of pole during carry and at plant and so on so he could back up his theories well.
Talking to Kjell a couple of years ago he noted that “nowadays the vaulters keep their lower hand where I kept with my highest. That says a lot about the development of the poles over time”. He also was quite realistic about his own performance noticing that giving todays circumstances he did not think that he could have jumped 6 m but about 590 should have been possible. The obvious reason of course his relative lack of speed.
I am certain that Knut and I know that Kjell would be strongly in opposition to the madness concept of pre-jump but they would certainly support the idea of free take off, especially with the underline that Petrov make; it should be felt like you are taking off before the pole hits the end of the box which also should be interpreted that you should not take off before.
The drawing of Kjell’s vault that was published at pole vault power was well done. It can be seen directly that it is him.
When I look at his paper on pole vault technique from that time and recall our discussions a decade thereafter I think it is fair to say that he is the original Petrov.
The other nations, first the Finns, then the French and later the Russians I guess studied Isaksson and the Russians with their resources were simply able to deduct what they saw and put the analysis to work in a systematic way so I do not think that they stole anything from Knut. They interpreted what they saw.
