Did anyone get the cash?:

I have read a few on here saying they can force it into giving a bad fix. Is this if you don't use the auto-verify feature? Or if you downgrade the rigor of the setting in an attempt to get a shot? Is there an actual contest entry rule form on this?
I'm not after the $10k, just wondering if anyone actually did get the auto-verify to fail...?
For what it is worth, The Javad people engineered a data flow into these, that AUTOMATICALLY let them reach a particular CONFIDENCE level, and certainty, and accuracy. Then, it automatically stores the point. And then, it restarts, on it's own. And can sit, untended, for a couple of days, saving one shot after another. (With a bit of backup power) and they messed about with this, to FIND a setting that they could NOT break it.
This was all figured out, in the ONE EPOCH per second rate.
So, this whole 10 k warranty, is based on hard data.
Spooky huh?
All the bad fixes, I have gotten, were gotten with the thing WAY tuned down, so it does not do it's whole double check thing. RUNS VERY FAST like this.
And, I was TRYING to bust it. I was doing it while tying building corners, (Where I can find the busts) Shoot ALL roof corners, under trees etc. And, then you find one not quite square. Low liability shots. Away from the property lines.
Have fun.

Detect conditions that would indicate a bad fix, and prevent the user from shooting if it does.
I know that sounds an oversimplification but that is a good simple check. Sure people can detect bad fixes manually and even set thresholds in their DC software but the automated part is way cool. Someone showed me that in some varied conditions and it appeared to work as promised.
I would doubt that anyone could ever collect, as it would be like a guarantee that one will no get bugs on their teeth when riding their motorcycle but only if the shield is down. Does it guarantee that no bugs will ever hit the shield? No, but it prevents them from hitting your teeth.
So does the feature mean that the rover will never get a bad fix... who knows (if a rover is fix free then why have such a feature)... .but (if the feature is turned on) will it prevent you from storing a bad shot due to a bad fix? Sounds like it does just that.
Yes, it will just keep starting over and never allow you to save the shot even if you want to. But you can turn the settings to accept float or fixed, or standalone (which some claim is better than float) , which is essential for rough locating things like a streambed under heavy canopy. Then you might get the occasional fixed position mixed with a bunch of lesser quality but good enough for the purpose. So, your technicians (or you) can still change the settings on you in the field and get the shot that shouldn't be got. Be careful out there.
Ok, I decided to make one of my settings "10k".
And, you know, it's been several generations of the software ago, since the 10k challenge was issued.
What would be a modern equivalent of those settings?
And, having used it for a while, what do you think of allowing the confidence counter to count up, the SAME as it does at the beginning of the observation?
For important shots, I have confidence set at 25.
It might be useful to give it a confidence counter check, at the end as well... At 5 Hz, maybe a confidence of 5? And for points that are critical, a 10?
It is amazing how fast this thing works, even in poor environments.
Most of my jobs have a dozen or so points that I want a "to the moon and back" confidence.
"He that hateth suretyship Is sure"
Or, "some points we want to be very confident of."
