Skin fold calipers, in the best possible case scenario when administered by a trained expert, have such a significant margin of error as to make them functionally useless. I strongly discourage you from lending any credence whatsoever to their measurements when determining your plans regarding training and nutrition.

See my other comment regarding the smart scales, but it's the same situation. They're not "always consistently wrong by the same amount" per individual. If so, then yes, that would be useful for tracking trends. Sadly they are not

As an amateur who has used them enough to get repeatable results, I strongly disagree with you. Yes they are not accurate but they can be precise enough to track progress when the scale is flat or up due to a recomp.

You can certainly pinch the same spot on the same day and get the same number a few times in a row, sure. But as your body changes you become a different organism. It’s not always going to be consistently wrong in the same way. Self administering the skin fold test makes the problem even worse.

Setting aside the fact that they are neither precise nor accurate at tracking trends, why are you recomping?

No really, let’s think about why you’re changing your body. Is it for a strength sport? Is it to improve your health? Is it to become more muscular? Do you want to run faster?

Because all of these things are completely self evident. Simply take a step back and examine whether or not you are actually making progress towards your goals. Whether you are stronger, faster, etc. If your doctor is happy with your new bloodwork.

All of the various bf% scams are so ridiculous at the outset because in fitness, we have such specific tangible goals. There’s no situation where having a figure for your bf% actually assists or informs you in any way. If you are achieving your goals in fact then the number shouldn’t dissuade you. If you are not achieving your goals in fact, then you shouldn’t let the number gaslight you about it and make you feel better. You need to make adjustments based on your actual results, not on something as nebulous and abstracted as bf%.

Especially not when the best, most expensive methods can at best tell you your number within six percent. Which is completely absurd. That 8% vs 14%. Literally guessing a number while looking in a mirror is more accurate for the purpose of tracking progress

I don’t care if the calculated % is wrong and I don’t believe you about changes in error. A thinner subcutaneous fat layer will form a thinner pinch at the same load. I am aware that it is an indirect measure but nonetheless it helps me meet my goals.

What is there to believe or disbelieve when the problems of this method are so incredibly well documented? The body is not as simple as you’re portraying, the measurement can swing in either direction for many reasons over the course of months and years. Rely on these measurements at your own peril
