I have not listened to that podcast, but keep in mind their data is taken from returned results to the ITC database, also many of those armies submissions actually insert the wrong Primary faction. When I compile my lists I actually go through each list to make sure they match what is submitted and often players/TOs put in the wrong Primary faction. Daemons vs. CSM vs. Renegades and Space Marines vs. IG vs. Imperium cause tons of confusion for submitting making whatever data ITC/FLG uses somewhat suspect. It is clear that Daemons + CSM are currently dominating, but to the degree FLG claims is harder to come by.
