Zmap detecting more hosts than Nmap

We already talked a bit about it on 30C3, but I figured that since quite a lot
of folks weren't there, I'd move the discussion to nmap-dev.
On 30C3, I heard an interesting talk by J. Alex Halderman, the author of ZMap.
In his presentation, he - among other things - compared ZMap to Nmap, pointing
out that despite its stateless approach, his tool actually finds more hosts
compared to Nmap in its "aggresive" mode. His explanation can be found here:
My question is - is that an intended behavior? I'm asking because it's the
default mode in Zenmap and the Nmap's man page says:
If you are on a decent broadband or ethernet connection, I would recommend
always using -T4.
IMHO it should be noted in the documentation that -T4 gives less accuracy.
What do you guys think?
