Don't mean to necro this , but the issue is alive
Searching gives a variety from 0.08% to ~10%
MMR on an iphone 5 over calcs mileage by ~6% vs my Hammerhead Karoo GPS
I was running both to cross check the new Karoo
I will switch to the Karoo, when I upgrade, since having an $800 phone on the handlebars just doesn't seem like a good idea
not that there aren't others
It's all relative anyway, and the differences aren't critical , but I just like knowing where the numbers come from
