Only the very first Indys; SGI very quickly (a few months) moved from R4000
to 4400 and then 4600, which are the same speed as, or slightly faster
than, the R4K Indigo. But yes, I'd forgotten about the original R4000PC
Indy, and that would account for the story.

That's certainly true, so I'm glad that one of mine is an XS24 and another
is an Elan, although the R5K might make a difference even then, or so I
hear on comp.sys.sgi.
