Thanks for the schooling @Big_John and @73Coupe! And thank you 73Coupe for explaining your red X.

My prior comment wasn't really complete to what I was thinking.

I am aware that things can be measured to such precision, so perhaps I was focused due to some prior questions/comments in this thread about the machine work.
We all hear about machine shops not doing things correctly, on routine work.

In a past life, when I saw measurement sheets with an 'all same measurement' line like that, it was 50-50 across the group of technicians for whether they diligently measured each part or just trusted the process and spot-checked that parts were in spec (and if in spec, didn't bother to write the actual measurement).
And I sometimes got FAIR papers from outside vendors marked as in spec that clearly were not, per their measurement sheets.
And in my current life @Big_John, I'm dealing with some A2LA labs, and I find errors in their reports sometimes. (this problem seems to be following me!)

Paperwork that looks like it might have shortcuts makes my ears perk up.

The 0.0001" (ten thousandth) is usually the decimal place where the machining "limit" is specified, on automotive engines, as in low or high limit.

Yes, standard procedure for all journals and rod bores to be exactly the same, the entire width of each. I had a problem with rods being "bell ended" in one engine that I had machined long ago. They honed them bigger on one side than the other. That machinist I dealt with at the time was a bellend himself, lol.

On a Sunnen hone for example there is a dial gauge on the machine to check the bore diameter as you're honing it. They can then be measured after with a handheld diel bore indicator.

That data sheet would have gotten handed back to any of our techs if they had done it. No doubt... I can name a bunch of things on it that wouldn't fly. It's really just showing what the finished sizes are for the person assembling it and while I'd like to see it done a little differently, I could work with it.

We had a pretty good system for finding errors. Everything was done in Excel where an out of tolerance entry would highlight the cell. Then everything would go through an inspection before shipping and then even our shippers were trained to look things over. Mistakes would still go out once in a while. We're all human. I can't say how it is now... Someone else owns the place along with our competition's lab.

I've even had customers chew me out for mistakes that they (the customer) made... That was always interesting. But I digress...

All that said, if you are assembling the engine, you'd want to get out the bore gauge and micrometers and check everything yourself anyway.

I have this great right angle bore gauge that I bought for a song years ago to check bearing clearance.
