You could not make assumptions and buy an AEV Procal for $150 and fix the speedo. That will fix your shift points and mileage.
I'm guessing you're implying 150 bucks costs an arm and a leg..but it's worth it.

Pretty sure he is saying that because he drives a manual, the Procal will not affect his shift points (left leg on clutch, right arm on shifter)
He just wants an answer to his question about the margin of error. I don't know the answer but maybe somebody does.
