LGTM, I do think that is clearer, thanks for doing this. I also left a super-minor optional comment.

This is super minor, so I leave it up to you whether you think it clarifies or not. Feel free to disregard my pedantry :)

When I think of / I think of it as alternative meanings for something (e.g., "my mother/care-taker" being verbalized as "my mother-slash-care-taker"). What do you think of something like:

Suggested change

	"For data stream %s: %s based on [inc/dec cooldowns %s/%s, %d-%d threads, "
	+ "write index %s has all-time/recent/peak loads %g/%g/%g, current shards %d, "
	"For data stream %s: %s based on [inc/dec cooldowns %s/%s, %d-%d threads, "
	+ "write index %s has [all-time|recent|peak] loads [%g|%g|%g], current shards %d, "

To clarify that they are corresponding values, instead of potentially implying that the loads are conflated and perhaps mixed?

(I realize the irony of replacing the / with | since | already connotes an "or" meaning, hence why this is so minor and up to you whether to make any changes)

See, I'm not sure that I'd find your version more clear!

I don't think that / is only used for alternative meanings. It's also used in dates, for example. If I said that a broadband speed test had a result of 800/500 Mbps for download/upload, would that be confusing?

I think I'm going to respectfully suggest that we've spent enough time on this, we appear to have reached a point where there's a subjective difference on the clearest punctuation without a clear answer, and I'm just going to mash the merge button...

[dakrone]

That's totally reasonable! No worries at all, that's part of why I tried to couch it in optional language 😄
