Harold Brookshire was the brilliant designer of Voodoo and Ultradyne lobes.
Jones method places huge emphasis on pressure differentials at valve lifts for a given crankshaft degree.
I do believe this is the root of what matters: the actual pressures of the intake port vs cylinder vs exhaust port the engine has during that phase of the cycle.
This is why I STRONGLY believe there is no one LSA, every engine combination will be different.
