[Yak] Odometer correction math stuff

[Jkeenan(Yahoo Account)]

Brad,

I do something similar.  Here's an example:

Say I set my reading to 133 in my Cateye (Mity8) for my 16" wheels.

I go and do a twelve mile check against mile markers:

Mile markers =  12.0 miles
Odometer  =      12.84 miles

12.84 = X% of 12.0
X% = 12.84/12.0
X = 107.25 %  which means I'm registering 107.25% of what I should be.

Then the formula to get the correct mileage  becomes 133 = 107.25% of X (X 
being what it should be)
Solving for X we get X= 133/107.25%

X = my new setting of 124

Proof
124 (times) 107.25 = 133 (rounding)

Yup, then I go out and compare it to the mileage markers again.

Hope the..ummm..math helps.

P.S.  If that doesn't "compute" email me and I'll send you an excel 
spreadsheet so you can just  plug in the numbers.
