I don't follow I lead groups , plus I ride for fun , Sounds like you calculate a bit much and miss the visceral bit .. You sound like an advance rider course . Follow one once and the lead rider was a ride wamnker , and he cause more issues as as he was tying to be a mother duck with his students , and not allowing others to pass his group , thus causing him to be aggressive in his riding.
I pulled him up at Crossgate Cafe and had it out with him , he still got shitty but point out to him that with all his blocking he had ( lol) forgotten about his students .
Come to Spain ... lets see .. or Wales even.
