Yes. It assumes that low latency equals high throughput, which is not
always the case (in fact it is often not true). Now, mirrormanager
should be pointing you to a regional mirror to start with, so you should
probably check that (there could be a bad mirror listed or something
like that).
Well, down here in .ar you get MUCH better bandwidth (usually what you pay for) for LOCAL connections (*.ar) while you get, if you're lucky 60% of the paid bandwidth for international connections (with some exceptions, ie Google, Youtube, which have local servers-caching of some sort), due to all the traffic shaping and bandwidth limit rules applied to international connections.
For me, yum-fastestmirror works WONDERFUL.
Here's the output of installing gparted in 12 secs

vs 34 seconds without yum-fastestmirror

Of course for a small package like gparted it's no big deal, but you see the speeds are 3x better with yum-fastestmirror, and it suddenly turns into a lot of time when installing big packages...
So, I don't know about what approach it uses, but it works for me.
If you think the current measurements by yum-fastestmirror is broken in some instances, it's an opportunity to improve the algorithms (ie measuring the speed of retrieving updates/primary_db the first time it is run, from the nearest servers, first by domain name / country code and then geographically? (ie neighboring countries)
