> three roundtrips

Well, before we get to the Google Fonts CSS, we first have to open another connection there, do a TLS handshake, and maybe we even need to look that host up first before any of that.

True. I got the roundtrip terminology from Google's PageSpeed Insights tool, which AFAIK does not count the actual network roundtrips.

The one "logical" roundtrip (an additional request) would indeed count for many if you consider DNS, TCP and TLS handshakes.

Even more of a reason to get rid of them.
