Of course it's relevant as you stated it was a prime example of a rider who would have benefited from more rides. Jacob Fellows had numerous rides around Oxford, in practice (doing lap after lap following meetings) and racing, and he never progressed - there was no improvement, as the scores show. Why do you think an extra ride or two would have made the difference?
I get the essence of your original point, though, but perhaps using Fellows wasn't a good example.
