Streamlining the 3 phase system

This has not been touched yet. Improving the confidence level calculation (VSAPP-3562) and not clearing confidence levels when switching back to Phase-1 (VSAPP-3666) are still on @Michael Stazhkov list. Hopefully these things can be done soon.
Any way we can move this up the “to do” list - PLEASE??
I’ve tried to illustrate, somewhat, what kind of a horrible pain this is. It literally happens to us multiple times per day, every day, in rough terrain.

15-18 minutes or more of hard phase 1 and 2 work blitzed by a few rouge epochs. It makes no sense at all to be looking at a group of something like 266,565,0 and starting all over again on the confidence level.

Of course, that group is 99.9% solid with 565 seconds of separation, but this “bug” basically eliminates the entire rest of the process of getting through phases 2 & 3 (unless we wait another 20-30 minutes most likely). Even if we do try and wait it out, the likelihood of the same thing happening again is very high.

I think we hould get rid of the "confidence level" and just be based on time and epochs. I'm more concerned with time and checking it.
You’re right Clay. Confidence level means nothing really. I understand the premise of how is was incorporated, but it really adds nothing to the shot being confident or not. You can have many of those tricky “2 engine fixes” go all way through phase 1 & 2 and get to validation stage, with a “confidence” of 20, 30 or higher and the shot still be bad.

How many times have any of us every said or asked - “what was your confidence level on that shot”. Answer: never. We ask, “how many epochs” and much more importantly, “ how much TIME between epochs”. Time is absolutely, positively THE most important factor in determining weather a shot is solid or not. Give me one RTK group, with over 240 seconds of separation stored as first point, then a second session with basically any epochs where DTL gives me 0.04, or better and I’m walking away 100% confident in that coordinate.

Doing away w confidence counter... May or may not be the best final answer.
Reason is:
If my confidence counter is set at 10, or 15, and, it collects a group, that goes into phase 2, then I get a visual on the group. If the group size is small, or large, seems to be a rough indicator of general shot quality.
If it's small, over some time, often it only gets one observation. If those reset epochs from phase 1 all happen real fast, in an obstructed area, it will probably need multiple observations. If Shot scatter size is large, then multiple observations are also in order.
Also, if it's just a fnc corner, or such like, I don't care about high accuracy.
If it's a utility, I don't care.
Or, a loose rebar, up 8".
So, I use these things as general indicators.
