It's not really involved or difficult
When I recalibrate a build, I just go out on the highway here that has mile markers each mile. I go 10 miles. Let's say after the 10th mile, I have gained 1 mile too much on the odometer...that means you need to slow down the speedo cable approximately 10%. Then just get the 10% reducing adapter. I also use a watch with a second hand, to time each mile, or just hold it at a steady 60mph for those 10 miles, to see if the error is the same on speed, as well as "miles driven".
