Just watched your first video John.
Whilst I am in total admiration of your driving and car I think you are just too quick for those Club sessions. It's like a Premiership footballer playing in a Sunday league.
You are a lot quicker these days and that is evident from your cornering where you are driving the car through hard.
You are at race pace (I'm sure many of the cars racing would be slower) but you are having to negotiate very slow cars and that is risky (that Porsche on the brow comes to mind). If you were racing you would have to have ARDS training, protective clothing, helmet, no passenger etc etc. Also the people on track with you would have gone through the same training. You are coming up against complete novices who haven't even had a briefing about overtaking or lane discipline . Can you imagine a race with someone driving around in a Sunbeam Alpine filming over the screen and waving to mates!
You need to book some trackdays - you and your car deserve them.
I know these sessions are great fun and I don't want to be a kill-joy John but it's so obvious to anyone watching the video that you are too quick. I bet the marshals have opinions too.
