Assioma – New V2 Firmware For Super Accuracy

Favero have made public their new IAV Power system. This is an entirely new calculation algorithm for Favero and it bases power calculation on Instantaneous Angular Velocity (IAV).

Apple Watch + STRYD :: First Run and APPLE WATCH Accuracy

GPS Accuracy Test: Spartan ULTRA vs Polar M600 + more

This time 3 Polars and a Suunto SPARTAN¬†ULTRA¬†braved my ‘standardised’ GPS test route.

Garmin’s upcoming Fenix 4 is rumoured <here> to have a new and¬†improved¬†EXO-2 antennae.
