I'm only including " racial or ethnic origin;" which again requires a fairly complete/complex DNA analysis to determine.

As to main accurate, I'm happy if I'm 95% accurate because accuracy depends on complete knowledge of a subject and knowledge is expanding at a geometric rate, I doubt if anyone can stay 99% accurate given the rapid expansion of knowledge.
?
Consider the new magnetic phenomena...I had no idea it existed until it was mentioned here. I try to keep up with topics that interest me the most. I'm a lot more up to date on Clovis Amerind Culture and The Younger Dryas event then I am nuclear weapons.
?
I am extremely familiar with the electrical system in our 2001 Volvo S60 and am woefully and willfully ignorant on the electrical system of a gasoline powered 2025 Volvo anything.
?
Toyota apparently added CAN to the 2003 Echo, so my knowledge of 2001 Echoes would be mainly inaccurate, however that knowledge is "mainly accurate" for 2000 and 2002 Echos.
?
So mainly accurate is probably good enough for my life and goals.
?
Another real world example, let's say I need an emergency antenna for 3.58MHz, [300/3.58] divided by 2 would give me the approximate length of each leg of a dipole antenna in meters, and, while not perfect because of end effect and the effect of height over the earth and the conductivity of the earth below said dipole, the antenna would work reasonable well, probably as good as 95% as good as though I did everything absolutely right, measure the VSWR, adjust the leg length or change the height of the dipole to achieve a perfect 1:1 VSWR.
?
Of course that 1:1 VSWR would be at the end of a feedline and, unless I used a matching transformer to transform the 72~75 ohms of the antenna to 50 ohm coax, or a balan (balanced to unbalanced) transformer to couple to 75 ohm coax, I couldn't be certain the 1:1 was really 1:1. One can spend a lot of time tweaking minor variables that will have no discernable influence on behavior or function.
?
So, even if I do everything to the best of modern technology, it will only be 'mainly accurate.'
?
I'd stick a piece about engineering back in the days of the slide rule when everything was mainly accurate.

My Echo specs a tire pressure of 32 PSI. Will 32.1 or 31 or 33 make any difference in drivability? Gas mileage? Tire wear? Doubt it, don't care, is my gauge 100% accurate, can I trust it when it says 32PSI? We have 4 "identical" [of the same manufacturer bought at the same time...but are they the same inside?], they all give the same reading. Is it accurate? Is there a design flaw? How can I verify this one way or the other? My compressor also has gauges, they almost agree with our tire pressure gauges, they are about a half PSA [eye balling here] so which do I trust? Either? Both? Neither?
?
I consider ~1/2PSA to be "mainly accurate" with our instrumentation and have way too many other things to worry about then "Which gauge is the most accurate?"
?
Although I do wonder about the temperature effect on the little brass (probably brass, every gauge I've opened has brass) bulb that is filled, distended and the distortion produces the PSI indication.
?
Is it the same at 0F and 100F?
?
I've had to check tires at each extreme.
?
I won't go into "Which of my voltmeters is really 100% accurate." I know which one I trust the most, it gets checked at the EE instrumentation and measurement lab every 6 months or so, has been accurate since March 1974, I expect any gross failure will be obvious...could be wrong.
?
Or consider an oscilloscope, assuming the inards are 100% accurate, how accurate can I read a line of illuminated phosphor or simulation on a LCD screen.
?
The line has a physical width, can I be certain it's 1V or might it be 1.001V or 99.09V. Assuming 1V is mainly accurate is probably the most logical thing to do.
?
Although only a fool or new tech would try to achieve more then 0.1V mainly accurate on most scopes because they are not designed to give 5 digit accuracy.
?
I suspect if you are honest, you'll admit most decisions in your life are based on the "mainly accurate" concept.
?
BTW, I didn't come up with 'mainly accurate' it came from a presentation by some NASA/USAF engineers to my engineering class.
?
One older guy said something like "Striving for perfection is a waste of time because you will never know all the variables to even 6 places, go for the best data you can obtain, do your math right and it will work out."
?
Which can be translate to "mainly right."

The orthopedist who replaced my knees had many responsibilities....some shared with other people like the anathesthologist. [God I wish I could SPELL!]
?
But neither had ran into someone with congenital?methemoglobinemia [look it up, I am not wasting 20 pages with the boring details, let's just say my blood is a bit messed up]. They were uncertain how to sedate me for surgery. The normal method is? spinal block but the drug used might trigger a massive MH event...so they played it safe and knocked me out with a "probably safe medication." I had to sign a waiver acknowledging the limited knowledge on MH triggers.?
?
Did they fail in their responsibility? My knees had to be replaced or I'd be in a wheel chair now.
?
They went with the best data they could find, mainly accurate might well apply.
?
And no one in the hospital knew a single color pulse oximeter is useless with MH attacks. I know quite a bit about MH, probably more then any single doctor or nurse because I have MH. I have over a terabyte of data on MH. There was honest to God near panic when I handed them the paperwork detailing weaknesses of single color pulse oximeters. They don't work too well on carbon monoxide poisoning either. I probably had the only dual color pulse oximeters in the city, quite likely the state. All because a former EE classmate works for a company that makes medical gear, I told him over lunch and he had his team design a dual color pulse oximeter and gave me one. They used theirs and mine, wanted to keep mine because I have cousins with MH and they might show up at the hospital. It might be selfish but I kept mine.?
?
They bought 10.

I've been pulled from swimming pools 3 or 4 times because the lifeguard thought I was having a heart attack because I'd gone cyonotic all over. Big Bad Bummer. Cold, intense emotion, fear, many solvents, can trigger MH events. Look up Blue Fugate. forget their geneology, they've got it all wrong. A nephew did not marry his aunt, he married his first cousin on his mothers side. BTW, many states allow first cousin marriages, only NC forbides double first cousin marriages.Bet you didn't know that. That's part of my mainly accurate knowledge of marriage laws in the USA. BTW, I married a nice woman from Northern Kentucky, totally unrelated, who puts up with me and my odd interests. I mean what normal EE cares about "Why did Clovis Culture end?"
?
I could go on but I've beat this dead horse into nice jerky quite well...
