So do these (+/- 10ms) add or are they a universal “+/- 10ms from the actual time on stratum 0?”

I believe it's n+stratum level.

Each stratum queries the stratum before it, so delays will be compounded the deeper you go but a stratum 3 for example could be more accurate then a stratum 2 as you will be querying more clients to get a more accurate reading.

At least that's my understanding.

@C0D4 That’s how it seemed, but not how the video presented it. I just wanted to make sure I was getting it. Thanks!!

@zvyn I’m JUST learning about it

I thought stratum 15 was an error condition indicating an un-referenced clock?

Also the errors won’t just add could be RMS or some complex formula.

@muttley isn't that 16? Pretty sure it ones to 16 🤔
Don't make me google this.
