Just to clarify, 40, 120, 200 suggests a Russian Plath SOLD sextant copy, either bubble, or gyro. If ‘GPS Spoof Pro’ is set to ‘Pause’ after the 120-second shot, subtracting 15.coslat.sine azimuth from the ‘GPS Spoof’ altitude should give a value comparable with the sextant altitude at mid-time. You will no doubt have read these: The SOLD KM2 Bubble Sextant | The Nautical Sextant (sextantbook.com)
