For info Chaps.
As an organiser and senior Instructor on some track days.
ANYONE found timing is sent home.
The reason for this is that if there is need to use the Public imdemnity insurance, (which all organisers and circuits need) and it is proven that timing was taking place, then the insurance is void!
So please respect the organisers rules as they are in place for a reason.
Have fun, learn circuits and technique on track days, maybe even run in new race engines etc.
But full-on hot laps and timing should be left for test sessions, there are enough around. In this way then you can really see where you and your mota are in terms of competitivity.
Enjoy!...
