This is like saying a car’s speed is determined by wheel circumference and how fast they turn, while completely ignoring the engine producing the power.
Secret formulas mean you are either an evil scientist, a 1950’s soviet, or a new internet Guru. This is where I stop listening, sorry.
Obviously everything comes down to the power output when the foot strikes the ground a V8 will beat a 4 cylinder. The fundamental question is what’s more important for maximal power output; making sure you put your body into correct position to apply that force or producing the force itself without even considering what you’re doing during the rest of the running action.
To be a new internet Guru I would have to be spamming, trying to sell something or saying how. I have never said anything about how to do it. The job of a coach is to determine the best way to teach mechanics that allows for maximal power output to create SL while minimizing SF. I have my beliefs and you obviously have yours.
I liked your car analogy though. I hope we would all agree an elite sprinter is a V8 engine that is what this discussion was about. To answer your question Bolt does in fact have larger radius tires. Therefore someone with smaller tires (Gay) does in fact either need to get larger ones and keep the same rotation speeds or get his tires to rotate faster with the same radius to beat Bolt. The question for their coaches is how they do that.
Please remember this discussion was about How to beat Bolt… not how to make an average sprinter faster. In that case I would agree let’s look at the size of the engine, but in the end efficiency to apply power and reduce wasted time must be addressed.
