Not sure how this got here. I meant for it to be in General. If it could be moved, that would be great.
Our Series is a bit weird in that we've never had an affinity for SCCA classing, having operated with our own classing system for over a decade now. Our event sizes are just too small (80 to 90) to support SCCA's granularity and the course layouts permitted by our venue are too small and tight to map well against the the datasets that drive PAX values.
Our system has served us well over the years, providing a number of benefits:
easy to access and understand for beginners who just want to give it a shot
doesn't force a rigid upgrade path, recognizing that cars are being built for multiple purposes (track, hardparking, etc.)
small number of well-populated classes with solid competition
Another Ontari0-based group using AxTime, began using a tailored version of our approach in 2016 and I believe they were happy with it.
This year, our system underwent its biggest change in a long time as we changed how we put cars in base classes. The change was spurred by a desire to further reduce the exercise of judgement by us (SCCA obviously still does its thing).
If you have any questions, don't hesitate.
