OK, I didn't know that.

This could be verified by playing back one and the same audio file either in SM and in NM and listen for differences.
Possibly there's something in it, don't know.

But I am pretty sure that it doesn't make a difference in ripping - ripping is much more a function of the CD drive than the OS and any rate is heavily laced with error correction, and can easily be checked on bit-perfect identity. Its when you start to turn it into analog audio where variations can occor (and in practise do; otherwise there would be no difference between a 100$ DAC and a 10,000$ DAC, right? ).

I think you have got the right idea here.
Re-writing the disc can reduce the amount of digital jitter that the CD player has to cope with. Subjectively this will have more of an audible effect on cheaper - less technically correct players that are more sensitive to jitter related effects.
I have heard of people in the past saying to burn audio CD's at a slower burn rate is a good idea. The idea of using safe mode to reduce the amount of jitter on the CD seems perfectly valid.

Of course all digital sound is perfect right?
And the world is flat.

The jitter on the CD is what someone else called 'different lengths of bits/pits'. And rewriting it doesn't make a hoot of difference - some get better, some get worse. It's a stochastic process. But that's irrelevant for the replay process anyway. The important thing is that no bits are missed, and the subsequent formatting in words and frames will take care of the lengths. Also, the final impact for jitter will come from the DAC of course.
Ripping at slow speed is done to avoid lots of errors from a not-so-hot drive. With more errors, the drive has to repeatedly re-read the data to get it right which can actually lead to longer read times than with a slower read speed.
Unless there are unrecoverable errors (which will be VERY audible), the recoverable errors have no impact on the final result.

Before this, your post was perfectly sensible. Why did you have to put something in nobody said?
It just detracts from the believeability of your post.

This is a misconception, the jitter is not "on" the cd, itīs the transports output where the jitter is generated.

Well then, rip something that's in the public domain, and post that.

I beleive <, = 30 s clips are considered "fair use" even for copywrite protected music

I would have to own a CD which is in the public domain. I do not.

I am in Australia. We are not allowed to do anything related to copywrite. Except buy it.
