kolesa doteraz u mna vzdy spolahlivejsie ako GPS, meracim pasmom zmeriam 5-6 otociek kolesa, vydelis kolko je 1otoc - vysledok do strojceka

Using a measured course to fine-tune your setting
A comparison of a cyclecomputer's distance reading with a mile markers over stretch of road, or with
GPS readings, can dial in the accuracy even closer. Divide the actual distance by the cyclometer's mileage reading, then multiply your calibration number by the result to get a corrected calibration number. It is best to measure over a distance of 10 miles or more to reduce round-off error and to avoid using inaccurately-placed mileposts. (The highway department generally avoids placing them in the middle of driveways and intersections...)
[Actual Distance] / [Cyclometer Reading] * [Old Calibration Number] = [New Calibration Number]
velku chybu clovek neurobi ked si zoberie za vzor:
