Wow - a whole lot of calculations that are absolutely pointless because they assume the speedo is accurate from the factory - which in my experience, it's not.
If you REALLY want to know there are only two ways:
- time over distance with a stopwatch
- GPS (and even this may not be accurate enough)
We're really only talking about a few % here - you need a REALLY good measurement. Even police radar may be off by enough to not be used.

Another assumption is that your tires are at a true 33" or whatever, which they usually arent, and that they stay at that, which they dont with wear.
I was just giving my 2 cents. The point I was trying to get across was with 4.88's and 33" it brought my speedometer back close enough to what it was before i tinkered with it.
