"The winner, with an impressive 102.3 feet, was John Evers, Professional Surveyor from Ohio. John’s submission varied only one hundredth of a foot from the RTK derived distance - a ratio of error of more than 1:10,000."
Now, this has me wondering... does he keep the RMS in his pocket, or was he borned with LEAST SQUARES in the back of his head?
Either way, I need to hire some people with this extraordinary Talent.
Congrats, to John!

It's called a lucky swag. I'd hire him, but not for surveying. I'd take him to a casino and let his lucky guesses do their stuff..! 😉
All this time, and I thought it was in his feet, or something!
One hundredth of a foot, he must have worn his extra thick socks, and not his normal socks that day.
Yes, Yes, That's got to be it! Thick Socks!
funny pacing story..
Sorry for the hijack..
Back in the "B.C." dates (before computers) I was a lowly tail-chainman. We did a lot of chaining.
On construction projects "fifties 'n hunnerds" was the command. I had a little yellow Kiel rubbed on the chain's fifty mark so I could see it as it rushed by in the dirt. I would always slap my boot down on it and holler "chain" as I picked up the chain. Accidently once the PC was just fixing to take his last step as I stepped on the chain and it yanked it out of hand.
As the day rolled on I did it a couple of more times just to get a rise out of the PC. We messed with each other all the time and it wasn't taken as obtuse, but we always tried to see who could "out do" the other.
The day got hot and sweaty and chatter was to a minimum. I hadn't yanked the chain out of the PC's hand for a while and I could tell by his side glances that he was expecting it...as fifty started to slide past I saw him take a big step and "lean" into it like he was going to yank the chain real hard.
I didn't step on the chain.
Too late. He had already leaned back and tried to yank on a loose chain. He yanked, but wound up on his butt in the dirt.
All I could say softly was....."chain"..;-)

And, who is not to laugh?
He he he
That sounds like how a crew should run.

0.01 ft .... RTK :-S
Bill,
The error potential was definitely there for it to be in the RTK and for John to have been right. Hard to say. 🙂
I worked one time along a 19 mile stretch of highway setting RP's for a road re-construction project.
We had 1 rodman on each side of the roadway and an instrument operator occupying the control. I was one of the rodman setting RP's. The process was to give the PC a shot on the last RP set, then pace ahead 100' and clear a spot for the next station, while the other guy was setting his RP.
You cannot imagine how many times, I paced 100' ahead, kicked the duff away, and placed the rod exactly where the RP was supposed to be. Me and the other rodman had a contest going, each time we did that the other guy owed you a 12 pack of beer.
We would each do this about 4 times a day and it seemed to balance out. I never saw any beer.
What they don't say is the RTK distance was a single epoch point 18 miles outside the localization. ..
easy bionic, easy. lol.
I can certify that the baseline distance determined by RTK met all of the rules and guidelines promulgated by the International Federation of Pacing.
