And yet some members swear by them, post about them and lead other members that there magical slide ruler calculations are perfect and if you’re fails, you did something wrong.
To an extent I agree .
that said, uniquely, the Moroso calculator has always been pretty accurate. It’s especally accurate to a car that is well sorted out to run what it’s capable.
I think Dwayne has said a solid bracket type deal that is within 10% of the Moroso calculator is doing a good job. Stock and super stock type stuff get well inside that 10% window.
Nothing is the Bible except a time slip, but if anything I have runs within 10% of that Moroso calculator, I am happy.
Each to his own
