I know this without being there, 70 to 80 is the usually pace between curves. If he was going over the yellow lines around the corners then the only way for him to keep up was to ride fast between them. Having someone else chime in won't resolve anything.

I do think he owes the group an apology and I'm glad this issue was resolved here instead of in the original thread.
