I dare....
Never met you in person Dennis but sure enough I'm impressed by what I've seen from you in the 300.
However I would like to quote "Earl of Rochester":
Gunter needed someone to tell hem that what he was doing was terrific for his age but that he needed to modify his display to match his changing skill level.
Professional performers often review their work on video and engage in critical analysis with those similarly experience in their respective fields - maybe all Gunter needed was a friend to talk him through developing something a little milder?
