Here is a JMT v3 screencast of the problem. The T2 is on a NGS control point and reads close to publish coordinates. When I pull the coordinates from design points in stakeout JMT shifts the design coordinate 0.5 feet east. https://drive.google.com/file/d/14bkZByw4VuqJY52lph79XILlHpFMU3uO/view
Easting Error in Stakeout with JMT

Dear Ken,
Does the offset in grid system or in WGS84/NAD83 too?

Yuri, here is the link to the control point. I have used this point for years and it matches the CORS better than most. https://www.ngs.noaa.gov/cgi-bin/ds_mark.prl?PidBox=JE1878
May be I explained the idea wrong, could you export the coordinates in WGS84/NAD83 - there are Latitude/Longitude fields in export. And then compare the result with OPUS coordinates
When I export the survey points and choose Original WGS84 Easting i get 94°27’24.15027”. If I choose WGS84 Easting I get 94°27’ 24.19254. Choose easting=2801014.258 vs 2801014.207 published, good. If enter an easting of 2801014.207 as a design point stakeout tells me to go 0.5’ east. The east coordinate on the stakeout screen is 2801013.706.
The published value is NAD 83(1997) POSITION- 38 59 00.07152(N) 094 27 24.15088(W) ADJUSTED
