I work with precise measurements a lot in manufacturing. We do a fair amount of gage reproducibility and repeatability (o=operator, e=equipment). You’d be amazed at the resistance to this basic activity.

I’ve often wondered why many papers do not print their gage r&r results for the equipment they are using in their experiments. I think sometimes if they did show the results it might lead to the paper’s results likely being debunked.

It makes me wonder if the physics might be easier to resolve or could arrive at a different result if it was considered.

The fact that this writer mentions the precision of the equipment tells me that he is at least aware of it.

It's reflected in the use of error bars. A measurement shown without an error bar may be discarded as untrustworthy and shouldn't have been published in the first place, unless we're talking popular press.
