Hi Res: Scope lowers bandwidth and averages some crap to pretend to be better quality.
Average: Scope removes data and averages some other crap to pretend to be better quality.Despite how you translate it at some time each of these tools will be found to be indispensable !
Those explanation are not wrong, therefore they are accurate.
While this case is certainly not a thing in court of justice, but still, leaving some important information out can make an explanation inaccurate or at least badly misleading, even if the part that is told is not wrong/lie/incorrect in itself.

I calibrated the new x100 probe I got, the BK PR2000B. It has a tiny hump at the start of the square waves. I read somewhere that's supposed to be a good thing, but I dunno. Is that true, or does this probe suck? 1 out of 4 of my TA131 probes I bought does the same thing:
Oh yeah, and I love the simplicity of using that zoom feature as above.
Does the 100x probe compensation adjustment range spec adequately cover the SDS1104X-E input spec of 15 pF ±2 pF ?
When using the Auto Setup, a simple "back/undo" type arrow poops up on the bottom soft menu. You can quickly undo the auto settings, or click default to reset all. I dig it.

Um, so does the Rigol.

The manual says 10 - 30 pF, so it certainly should. I attached the specs.
Good.
Probe compensation adjustment can be influenced by the pressure placed onto the trimmer with the adjustment tool.
Check this is not the case with your issue. Sometimes to get compensation 'perfect' it requires more than a single attempt.
Josh, thanks for the comparisons thus far. Interesting stuff.
Hey! The Rigol has an overshoot measurement, pretty handy while calibrating probes! I got it under 1%, don't remember the exact number, but that suggests about 1 LSB, which seems good enough for me.
I calibrated the probes when it arrived, each probe for each channel with the corresponding color and I just check every once in a while, haven't need to tweak it any further than that.

When I had the Rigol, I calibrated the first probe, and retested it on each channel. It didn't need any tweaking at all once calibrated. Even switching one of my TA131 probes from the Rigol to the Siglent surprisingly didn't need any adjusting.

Yes, I also did that test, and had the same results, but better to be safe, and even better have the color on your probe tip matching the display (leave aside the two blue channels)

Another thing about 'accurately' compensating probes, set the timebase to say 200us or faster so to stretch the peak of the square wave and also use plenty of amplitude so to magnify the uncompensated portion for finer adjustments.
You might have to shift the Hor and 0V positions but the result is worth it. Also DO assign the correct colored rings to the probes so that they go back onto the same inputs.
What a lot of ferking about I hear you say, well I do this for every DSO I sell !
I also need to figure out how useful the differential probe I got is. At x50 it goes to 130V, and x500 it goes to 1300V. I feel like this guy is going to collect some dust. I guess it's a good thing it comes in fancy case, right?
Here's another example of the speed (by mistake). This is the 1 Pico probe that does the same thing as the BK probe. I shoved in the memory stick and hit the print button. It worked fast enough that it captured the screen with the USB message still on, and I didn't even realize it captured anything yet, so I hit the button again and captured two images. Oops.
Well, it sounded like you had already determined that you didn't need to make differential measurements, just relative to ground.
