Yesterday whined about #4 (#189) on my day 2 race being off.
Val, who had the same control on her course, sent me a
link to her GPS routes.
I know next to nothing about GPS and tracking routes, so I'm
not sure how much of this is GPS error, but #4 is clearly high,
even if you take the local error as the deviation of Val's route
from the trail. Since she is pretty close to the center of
the circle on #1-3, perhaps there is some underlying local
distortion of the map.
Looking at #7, which was one I felt may have been too far
east, and which I lost another 2 minutes, we see Val
punching on the edge of the circle to the east. Again,
this may all be GPS or calibration error, but it would be
nice to think I could blame some sort of cosmic distortion
for my lousy run.
Vlad also complained about #8 (#213) being too far
east. I'm not sure if Val boomed that one, or if it really
was. Also, she had no trouble going thru the phantom
marsh near her #6 and our #6 (#199).
