Below a conversation transcript that I took briefly Âoff forumÂ, but now
time to post it I think.
You can read from the bottom of the transcript below if you are interested.
Briefly in summary, it seems to me that since 5.3.5 or earlier, therion loop
closure results in grossly distorted out
to try 5.3.12

Hi Bruce,
I
I got some unexpected results recently when I added some very rough gps
coordinates to my survey for a cave that has three entrances. Because they
are approximate I added some estimates of standard errors as below, so that
I could get Therion to factor the relative accuracy into the loop closure.
Hi Bruce,
I have hundreds of fixed points with different accuarcy and never
noticed the effect you are describing. However, I am not fixing directly
the coordinates of stations of my survey. I always create independant
fixed points and then equate them to the survey stations. In your case,
