Is mark minervini a legit trader or another webinar/marketing guy?

Does anyone know for sure that Mark Minervini has made great returns from trading or he is just another marketing guy selling his books and webinar?

Mark Minervini won US investing champion competition in the mid 90s and rode the tech bubble to glory.

But he doesn’t actively talk about his record in the past decade, so probably not as spectacular now. His books are good, solid concepts mostly about volatility contraction.

He has participated again US investing competition for 2021 with $1 million.
