My regen is usually set to about 50%. Up in the air, it is a matter of comfort and preference, it is possible to get used to any setting. Instead, I set my regen based on the corner entry.
Too much regen will make the rear-end skid when you have no rear-end traction and will make it difficult to roll through the high-speed corners smoothly. You'd have to compensate with throttle.
Too little regen will not slow you down and will not transfer the weight forward to increase the front-end traction during the corner entry into tighter low-speed corners. You'd have to compensate with the rear brake.
Ideally, this setting should be fine-tuned for each track and track condition. And, if you are good at paying attention and multitasking, perhaps the regen map should be switched based on which corner you are entering. Ideally, that regen should be higher at lower speeds. Maybe it already is. On gas bikes we do not enter all turns in third gear, right? I hope someone at Stark will read this.
