My 0.04' is better than yours.
Leica is more accurate.
Least Squares is a system of changing numbers, so that error is put where it belongs.
It's value is greatly enhanced, with redundant measurements.
What good is it, if you measure it right the first time?
Of course, the answer is:?ÿ
0.04'.?ÿ

2H is WAY better than 4H for shading and cross hatching!
My favorite Kent story involved a resurvey he performed of a residential lot somewhere in Austin.?ÿ Of course another recent adjoining lot survey had to be decimated and discounted with sharp critique to make Kent's report rise to his own standards.?ÿ I've cautioned Kent several times about creating a perfect theory in conditions where no perfection exists.?ÿ But that is just his meticulous nature I guess.
The one fly-in-the-ointment for Kent's version was the position of two original pins at the rear of the lot.?ÿ Their location was contrary to where Kent wanted them to be.?ÿ These pins sat at the bottom a steep drop, some two or three tenths further than he thought they should be.?ÿ Kent surmised that due to the derived composition of the clay soil the pins had "drifted" downhill.?ÿ This perfectly explained why they didn't seem to fit well with Kent's "perfect" solution.?ÿ His report contained about a dozen pages explaining the soil conditions and how the clay had drifted.
Now Kent and I share a good friendship that is somewhat contrary to the crap I always shoveled his direction here on the RPLStoday.?ÿ Our frequent conversations are nothing like the bickering one would see in any given post.?ÿ But I had to speak up on this one.
I tried to tell him there were probably just as many high P.I. soils here in OK as there were in TX.?ÿ I have never seen a clay under burden shift with gravity in any perceivable amount in a relatively short time.?ÿ Maybe hundreds of years, but three tenths in 50 years seemed unlikely.?ÿ
I think the last straw was when I pointed out two pins 100' apart sliding down a hill the exact same distance was a stretch even I couldn't make...and I'm a semi-professional prevaricator! ?ÿ
That was one where Kent and I just had to "agree to disagree".?ÿ 😉
Those that used pencils might find this humorous:
I was an instrument man for a PC that had absolutely no sense of humor.?ÿ Of course this made me mess with him as much as I could.
He used an old lead-holder for his notes.?ÿ He always kept in the truck a tube of 2H or even H for his note keeping.?ÿ I use to swap his 2H lead for 6H lead in the truck.?ÿ For those that might remember, using 6H lead is like trying to draw with a 16 penny nail.
He never did figure out what I was doing.?ÿ He would throw away all the lead and blame the humidity in the truck for ruining the lead.?ÿ?ÿ
Speaking of fights. What exactly was the "bogus theory" Keith always railed against??ÿ In his later posts I don't think he identified his nemesis.
I think it had something to do with lines of protraction on original survey plats being held on a higher order than existing senior corners set by civil surveyors over the years after the original survey was performed.?ÿ There was also the sub-argument about whether a middle point set on a government line was to be set by line of sight or on a line of constant bearing.
Contact Holy Cow for any particulars about the latter. 😉
Lines are straight for a half mile at a time.?ÿ Sometimes for a full mile.?ÿ Nuff said.
Liars laid out the original Government monuments anyway.?ÿ The proof is in the pudding.
I started out using 2H for field notes because it was less smear-prone than softer leades, but the writing was so light that after a couple of years I switched to HB and still use it.
using 6H lead is like trying to draw with a 16 penny nail
6H was always the go to lead: Didn't have to sharpen as much; didn't smear as easily (especially for lefties); you could write really tiny. Our drafters would use a magnifying glass, to read the field notes...
If a 60 course description fails to close by 0.05' it contains an error.

I'm on the 2nd tube of epoxy, and it's no good either!
