0.5i is correct. Now fixed in the texinfo manual.

Thanks for the report!

This report applies to groff 1.22.3. The same issue exists in the latest groff in git.

The .ta section of the info manual states, "The start-up value of [.ta in] `gtroff' is `T 0.8i'."

However, this is not what groff itself reports:

$ echo '.tm \n[.tabs]' | groff -T ps
T36000u
$

Since the ps device has a resolution of 72000 units per inch, 36000u corresponds to 0.5i, not 0.8i.

I don't know which value is correct, only that they don't agree.
