I see, thanks for clarify. I have tested hold ICE on for uphills and by empirical data collected from same route that if uphill is not really steep/long you actually lose EV miles slightly compared to full EV ride. Don't know if anyone has noticed same effect?I think the "rules" allow a small amount so you have time to stop safety and take a photo The problem we had in the early days was people selecting hold going uphill to fudge their EV miles. It could often be spotted by low petrol MPG like photo above
Btw deleted my post as it was not proper for 50mile club rules. Pardon!
