Incorrect GPS Data

I have been noticing that many of my GPS distances are incorrect. This is different than the 4.10 issue where the distances do not update until you laser something.

I see a lot of front pins where I laser them, and the GPS information is showing the front of the green, or even in some cases further back (meaning the pin appears to be in front of the green, not on the front of the green).

I have done a reset on my device hoping to fix this, but the information still often enough appears incorrect that I just do not trust the GPS data on my device anymore. I did not have this issue on my Z80 on the same courses.

Is this incorrect course data, or is there something wrong with my device?
