Drop outs on iPhone are commn place. I plotted Harry's against VBox and PBox and was a significant difference at Spa |
Although I have tested a VBox at Silverstone and not against Harrys I wouldn't dissagree with you. You can see the speed suddenly jump in areas on my video almost as if the GPS signal has caught up all of a sudden.
Its 'reasonably' accurate and I use it to review my lines and where I am on and off the power more than anything else. The speed and time are just a guide.
