Sometimes the answers are not as simple as a golden nugget or reason.... Let's look at this from another perspective!
When Bubka broke the record for the first time in 1984 it was only 5.81 at the age of 21......
It took him 9 years to progress that height to 6.15 at the age of 30......
Till roughly 1991 he was under the Soviet System of basically treating and allowing their athletes to be science rats. (simplistic term)
His youth development was under strict instruction from top developmental coaches in the 100 and long jump. I'm guessing from age 12 till he picked up a pole (anyone know exact age he started vaulting?)
Lots of the stories I have heard (none of which are exactly about Bubka) are athletes being trained like the boxing character Drago in the Rocky series.
Young kids were enrolled in schools thats only purpose was to excel as athletes if they failed they were sent home. This is gymnastics, swimming, track etc.... They were set up for ideal and perfect development as youth atheltes. Do we get that here in the US?
Bubka was in a setting for his entire career of near perfect situations for development. The equivalent of our Olympic Training Center in Chula Vista since probably age 18 or earlier. Everything was available to him and it just so happened Vatali Petrov was the vault coach.
What if the coach at the center at was John Smith? Would Bubka have been the Bubka we know?
Here is an interesting question that only those (a very select few) that have jumped 6 meters can answer. If they had been the first to jump 5.81 and set records like Bubka did as they progressed to 6 meters what kind of emotional and mental high would they have been on? Would they have jumped higher if they had the same mental high from being the first the progress those heights? How aggressive and willing to try things do you get when your constantly breaking records and jumping higher? Every new height and success leads to more positive emotions and wiliness to push the envelop that much more.
If the WR when Bubka was 21 would have been let's say 6.15 would even Bubka had challenged the WR? Could he have lasted 10+ years to progress to 6.16? Data shows it took him 10 years of stress on his body. Could he have made it without the WR's, without the money he made, without the mental carrot of each WR is pay day? Would people have written him off when he went 3 years without jumping higher or are we seeing the same progression that we see in Renuld and Hooker that Bubka would have shown?
Our system in the US is what it is Athletes come out of college at the age of 22 to 23 which means if they can survive 10 years to age 32 to 33 than we will see what they can do. How many actually do that? Hartwig at age 31 jumped 6.03 meters, Tim Mack age 32 6.01, Toby Stevenson age 28 jumped 6.00, Brad Walker age 27 jumped 6.04, hooker age 27 jumped 6.06.
Finally Renaud at age 23 jumped 6.01 is he the next bubka? Can he last 10 years till age 31 to find out is the real answer. At age 22 he jumped 5.81 putting him near Bubka's record at age 21. Only time will tell if he can continue to 6.16.
The vault and ideology is as simple as get speed, grip high and get launched. Yes it is more complicated than that, but in the end thats all it is. The real question is HOW DO THESE VAULTERS SURVIVE LONG ENOUGH? The mind is an amazing and strange thing. One moment your on fire and the next your on a low. Maximize the emotional highs and minimize the emotional lows is the name of the game.
As a side note have you seen pictures of the facilities those athletes in Europe have? We have an old gym, vault area that is no longer big enough for a full approach, a weight room we built in an old shower room and phiso by begging and pleading people to help. Not being allowed to train others because the facility says no one else can train here. Till as a whole we have the same training club systems they have in Europe or when Bubka was in his prime it will make it more challenging to progress they way he did.
