Apart from other occasions, it's occurred each time I've used the Backup and Restore option, even though it failed (see above). When this happens, all my settings for Playlist grouping revert to Default, too!

For upsampled hi-res using a clean resampler, -b8192 often helps 176.4/192k content, -b16384 often helps >= 352.8k content, when coupled with some narrow windows, the result will be comparable to -8e and often better than -8p with much faster encoding speed.
Yeah, "often" - I didn't find it too predictable though ...

If one wants to enhance the encoder, then one could make it accept a -b"2048,4096,8192,16384" to do four encodes and pick the smallest file. (That's constant block size - variable is a way to go to implement, and besides you might for compatibility want to stick to constant.) I have no idea if such a construct would be effectively multithread-able.

What I wonder though: say you got a CDDA signal that is fairly well compressed using an 8-order predictor. Now upsample it to 88.2. Wouldn't that suggest that you could try to "compress as undersampled" and optimize coefficients on N-2, N-4, ..., N-14, and pin N-1, N-3, N-<odd> to zero?

Also, one could think up some smarter "-M-alike" thing to get out the larger parts of the "-pemr8 -A <tonsofthem>" gain for cheap. Say, brute-force some frames at "smart intervals" based on the performance of the previous brute-force'd choice and the encoder's guesstimate.

 
... but, someone's got to do it - and neither CPU nor storage is as expensive as when the codecs were new.
To all you computer science professors reading this - wouldn't there be some fun student projects from all this?  ;)
(Hm, "all" = "none" I guess.)

FLAC / Re: FLAC v1.4.x Performance Tests

Instead of changing the source code someone can simply write a "tips and tricks" guide or something similar. For example, video codecs also have guides for optimizing some specific contents (e.g. anime).

I think one can see that tones can be generated at arbitrary frequencies, and can be multi-tone, can be sweep etc, this will add a lot of complications. Also, if one has to use --lax to get close to subset -e performance it is also not very practical too.

For upsampled hi-res using a clean resampler, -b8192 often helps 176.4/192k content, -b16384 often helps >= 352.8k content, when coupled with some narrow windows, the result will be comparable to -8e and often better than -8p with much faster encoding speed.

So, something like -8b8192 -A "subdivide_tukey(3);blackman" may often help CDDA > 24/192 clean upsampling without a lot of trial and error or subdividing too many tukeys or doing some difficult gausswork, or increasing other symmetric parameters which may further slowdown decoding.
