Maybe you didn't read, or didn't understand, what I wrote :
"If you put together an American or European specialist of high level, and a Kenyan of high level, 10 meters BEFORE a barrier, and look where they are 10 meters AFTER the barrier, you can see that the technique of the American or European is very much better, but... the Kenyan is able to earn 3 meters in these 20m, including the barrier."
This is a FACT. All what we have to do, is to ask ourselves WHY this can happen, when the hurdles technique of European and American runners is obviously better.
To compare the hurdles technique of specialists of 400 hs with what happens in steeple is not fair, and is a big mistake. The technique totally changes when the speed changes : at the speed of 400m (about 10.2 meters per second) the distance of the attack is between 1.5 and 1.8 meters, and the most important type of training, when athletes have already a good technique, is the knowledge of the right RHYTHM. When an athlete has to change leg because of the fatigue, going, for example (I speak about the best in the world) from 13 steps to 14 steps, the length of every step becomes suddenly shorter of 18-20cm, and the distribution of this loss of length must be studied, because is one of the most important keys of the event. This fact can also explain because THERE IS NO RELATION BETWEEN SOME IMPROVEMENT IN 400m FLAT AND THE RESULT ON HURDLES. When athletes run the flat distance, the progressive loss of length per stride must not be controlled with mathematic parameters, like for hurdles, but can be controlled according to the level of fatigue only, and the feeling of the athlete. The distribution of the effort is more part of a specific temporal skill, than of a rhythmic skill.
For the best specialists of steeple, the speed is about 1.6 meters per second and the distance of attach is very much shorter. In steeple, it's not possible to speak about "Rhythm" : on the opposite, the athletes need to be able to adjust their action every time, because are in the middle of a group, can have variations of speed due to tactical changes during the race, and in any case the distance of the attack to the barriers never is longer than 1.20m (sometimes less than 1 meter, when the athlete is in group), and, how Malmo explained, the athletes have to jump higher, because a barrier is not a hurdle, and you can't risk any impact, how in the past happened with some of the BEST technical specialists (for example, Baumgartl in Montreal Olympics 1976, or Jager in Paris in 2015).
It's true that the ability to accelerate before every hurdle has an energetic cost, but the solution isn't NOT TO ACCELERATE, but training for supporting variations of speed during the race. This is what we do with the best Kenyans, and is what we don't do with the best European or American.
About the fact that it's easy to win when we coach strong athletes, we need to understand something very important :
a) Nobody can coach to the top of the World weak athletes. How I said several times, the best coach in the World never can change a donkey in a racing horse.
b) Can be easy with talented African to beat European or American with very less talent. But, when we speak about the best in the World, THE BEST NEED TO BEAT THE OTHER MOST TALENTED RUNNERS, WHO AT THE MOMENT ARE AFRICAN THEMSELVES. And, in this case, when the talent is the same, the difference is in the quality of their training.
So, please, stop writing stupidities like "when one coach working with African is able to take somebody running 18'in 5000m when junior transforming in top class athlete, this is a good coach". This situation simply doesn't exist (look at point A), these are two different things (like to say that a professor in University is good when is able to teach to some boy/girl of primary school making him a nuclear engineer) : one thing is not BETTER than the other, because in every role there are the best operators, the average operators and the bad operators, and in every role the best merit respect for their specific knowledge and ability.
This is the World, in spite of what many of you can think.
