You’re right that everyone has a different theory, but the data-driven answer is that you want 5-8% tire slip at launch. Too little spin and the engine bogs; too much and you're just wasting energy. With your weight and tire combo, focus on the "hit" first. If the car is hooking too hard and bogging, drop your launch RPM or increase PSI slightly. If it's spinning, add weight to the nose or drop the PSI. It’s all about the shock to the tires—don't chase a "perfect" number, chase the best 60-foot time.
