Not really.  Considering that:

1) iso downloads don't take yum upgrades into account, and
2) download statistics in general don't take local mirrors into account

Smolt numbers show the people that voluntarily submit profiles.
Download statistics show the number of downloads that hit the main
servers.  Neither can be used to derive estimators from the other.
