Last June, I was practicing staking out some points on a line from a pair of points I'd set. Since then, I've continued to make many redundant observations around the control network, and recently adjusted it in Star*net. Out of curiosity, I brought back into the file where my adjusted control resides, and looked at a bunch of offsets between the points I'd staked and the line. I was pleasantly surprised by what I found. 
The offsets measured from 0.00' to about 0.07', which is probably within the range of errors consistent with my wife holding the rod (no tripod). I don't recall them being anywhere near that close when I checked them just after I staked them. Far too early in the game to be patting myself on the back, but thought it good news to know I might be able to get lath placed accurately to within their own dimensions.:stakeout:
I know a lot of blokes that couldn't hold that tight.
Sounds like your wife did an excellent job.
0-20 mm.
I had a clients wife do the pole stuff once. He wouldn't but volunteered his wife.
She smoked like a chimney, shook like a leaf in a stiff breeze, but when she clamped the fag in her mouth and 2 hands on the pole it was absolutely rock solid and vertical.
I was amazed as I read and reread to the prism she was holding.
I have never had a more reliable, consistent and accurate person of any age or gender.
Women are highly capable people.
"She smoked like a chimney, shook like a leaf in a stiff breeze, but when she clamped the fag in her mouth and 2 hands on the pole it was absolutely rock solid and vertical. "
Uhhhhh. Strictly surveying? Correct? Sometimes your Aussie lingo makes us unsure of your precise meaning. ;-);-);-)
Wow - and her husband volunteered her services?
Every time you set up, do you reshoot and record the backsight distance between these two points in a direct and reversed observation and add it to the network?
Of course all his attempt at precision assumes you record, ambient temperature, atmospheric pressure and humidity at your instrument and observation point.

All the points in the developing control network have been direct and reverse; most more than one set. I've not done that with these stake out points though; they're just the record in SurvCE after you stake out the point (which I've only ever learned to do using a single face). They were all on fairly level terrain.
I always set the temp and pressure in the instrument at the beginning of each day (and again during the day if things are changing rapidly), but never recorded humidity. There's no place in the instrument set up to do that. I can imagine that humidity might affect the EDM, but how much would it have to change to have a significant effect?

A heavy cigarette smoker. Hands shook constantly when not holding anything as in the prism pole.
Fag (cigarette) in her mouth
All her shakes stopped when she held the prism pole. It was quite uncanny to see.
When we met she had a fag (cigarette) in her mouth which she then held between her fingers (the fag ie) and that was when I noticed her shake. It was as though she was waving someone goodbye and I began to imagine what lay ahead and saw accuracy being a hit and miss experience.
Yes all strictly surveying as described by local lore.
That was supposed to be a 'comment'. Hadn't realised I'd pressed wrong button!
Ah. Is this how it works. A 'comment' versus a 'reply' as it turned out below. Just testing. Please ignore!
Richard,
That was my attempt at being a bad boy. Altering your survey-related words to a sexual connotation sort of thing. Something about a two hand grip resulting in something being rock solid and vertical.
As Emily Natella used to say in old Saturday Night Live skits, "Nevermind."
Yes I knew where all that was coming from, heading.
I realised 'fag' could have other colloquialisms, so thought I'd best elaborate.
Daughter once exclaimed at all the beavers at a certain watery place in USA and wondered why everyone was staring at her.
Well, I for one got a good chuckle, and enjoyed the ride, and the double entendra (whether intentional or not).

The question is not if you ever did them D&R, the question is do you check them now, when you do side observations? Any measurement that you want to check later should be D&R, because otherwise it is not a true measurement. Things change over time. Guess you have to learn something else.

As did I. Fortunately, my wife doesn't smoke, but boy does she shake just fine. Just not holding the prism.:-D
