"...I am puzzled with your answer..."

Dear Laurent,

No need to worry - it was just self-irony.

But every joke has a serious background: the uninitiated tend to name things that they don't understand intuitively as "secret knowledge".

This applies to any métier.

With closer examination "secret knowledge" is simply the result of long, hard and systematic work:

"...I was only reporting results obtained in our team after many lengthly tests and benchmarks..."

In other words: before intuition there is a lot of iteration repetition.

I'm working hard to take myself not too serious.

I hope that helps ;-)

Edit: Minor change of wording.

My very best regards, Karl
