Reach vdop with a quadcoopter

Was curious if anyone in the EMLID sphere has any output data on GPS precision. (Tuffwing staff has promising results on a comparative study plot: https://emlid.com/tuffwing-reach/).

The vertical precision is great, but I suppose that is a best case scenario, I suppose I’m grasping for others’ experience with this on a quad?

thanks!

There is plenty of reports on this forum about the precision of the system.
