I ran multiple sessions with 2 PM3's(I had actually used PM2's also, but removed that data.

I have My one unit on point "A", which has been previously set.

On day one, I set the rover on point(800' away) "B", for about 7 minutes(it was getting dark and I wanted to leave, but I had a solution indicated)

On day 2, I again set on "B"(for about 40 minutes, with a unit on "A", and then proceed to set on "C"(for about 14 minutes and about 250' north of "B", then on another point about 150' west of "C" for about 10 minutes.

After adjustment, I have residuals of 0.35 feet on all of them("B", "C" & "D").

Okay . . . I disable the vector from "A" to "B", for the first day(7 minute occupation).

NOW all of a sudden the residuals are absolutely 0.00 for points "B", "C" & "D".

Now how could disabling the vector from "A" to "B", on the first day("A" is the control), have an effect, good or bad, on points "C" & "D", on the second day(again "A" is the control)?

BTW . . . Now, when I click on the vector from "A" to "B", I no longer have the option of enabling the first day's vector. Shouldn't the vector still be there(& just be "disabled")?
