better than the RTX.....
All CORS equipment is renewed with time...receiver and antenna...I assume these operators evaluate their equipment periodically
https://www.ngs.noaa.gov/CORS/
Accuracy - F9P accuracy is stated at 0.7mm +1mm per km.
At 20 miles (32km), then 0.7 mm + 32mm = 32.7mm (1.3") on a clear day.
but it appears to be better than the RTX
Either dealer has not maintained (replaced, correct coordinates) their equipment, RF interference, or this below is the issue.

Also, enter your coordinates, and click on upper tabs for more info; when satellites are just above the horizon, your accuracy improves. https://www.gnssplanning.com/#/settings When at higher elevations, accuracy decreases.
My biggest "challenge" was learning/realizing that I needed to use the NAD83 datum.
