Just use the calculator. They are more accurate than these morons getting in their cars and telling you what their speedo says. The calculators actually do the math with the correct formulas. Some guy just checking his speedo isn't as accurate. We all know that the speedo's are off more the faster you go.
Scotty asked if there were any REAL WORLD experiences with 4.10's and incorrect speedos. He also wanted this info because he didn't trust the calcs so I gave them. I posted my experiences and in no way were to reflect what others had done or experienced themselves. To come in calling us morons because we answered the question asked to the best of our knowledge is a little immature.
Anyway, looks like Spreadman will have to lock his own thread if it keeps up.
