May save you some time from posing the question on here…what’s my bodyfat %?
If you can’t get a consensus under 15% mean with +/-3% SD then decent chance the answer is too darn high.
Could also use the quick rule of thumb: waist-to-height ratio: keep it <=0.5 --see more info in the thread linked
Formulas are set up for english units…pounds and inches. Equations written out you can port to Excel if you are too cheap to run a DEXA or do a quick BIA (Inbody Scan or don’t have access). Also I’ve had decent agreement with BodPod and calipers as well. So average up the results of the equations and if the SD is tight you probably have a decent estimate. Post your mean +/- SD here and let’s see the agreement between the equations.

For some reason, I was mixed up on my inches (without thinking, I was thinking 70" was 5’, not 60"). So I was thinking damn, 5’7", 240 lbs with a 34" waist. I was questioning things at this point with the “only” 17.5" neck. I was thinking surely you must look like a IFBB pro.
The numbers make more sense at 6’5" lol. Still gaining 28 lbs and only an inch on the stomach is impressive.
Interesting and thanks for sharing. I ran these numbers for myself and came up with a mean of 20.88% and an SD of 1.96%. My most recent DEXA had me at 20.3%. That was a little over six months ago and I’m definitely leaner than I was then. My BIA scale (Renpho) puts me at between 18.5% and 19% depending on the day. My best estimate of where I actually am is somewhere between 19% and 20%.
To answer your question, IMO, human nature. Easier to rationalize a number than look in the mirror and conclude “whoa, I’ve some work to do”. Apologies to any body dymorphia folks (including me) if this conversation is triggering.
My comment has significant practical application when having measurements taken. You must be aware that that there might be too much variation in the measurement system to reply on the accuracy of the calculation, especially when changes are small.
This not a “heady” obscure consequence. I am all onboard if you have good application of statistics to aid in bodybuilding or powerlifting.
I like to make all make posts to have application thoughts.
Making a decision based on results from a Gage with too much measuring variation could lead to improper results. Few people acknowledge the existence of measuring system variation when they run the calculation through their excel speadsheet. Not to mention any understanding of significant digits when measuring is involved (not critical for % body fat in this case).
