As an avid fan, I would be more interested in a)- how modern squash players train b)- if they can give me feedback on my game via video. I once trained with a former World 80, he was a nephew of a former world-champion. His coaching and feedback on the game was 100 times better/different than the club's coach. Training with him for 15 days, I think, had 10x times more ROI than training with club coach. These professional players / coaches are miles ahead. His feedback on my game, racket skill, movement, and even on warm-up was so different. I had never warmed-up like that before and his prescribed exercises was so different and effective.
