^^ This... I wrote a database app many moons ago that I stored all my ride info in and I noticed that my avg time and speed were always off slightly. Came down to rounding from the computer and my db. I carried out digits 3 places for some off reason and the computer app only carried it out to 1. I changed my coding to only show a single digit east of the decimal and boom.....match.
