During Outland, nobody was doing 4 to 5k on average - the average, in top end gear, wasn't even 2k. Method's first Kil'jaeden kill, for example, see's the rogues not able to get above 2.5k, never mind the crazy numbers being quoted, and their uptime was very high. Against the Lich King on heroic, Paragon's top DK was managing around 14k (slightly less) so, again, the 20k number is grossly overstated, even considering the downtime on Arthas. As for Cataclysm, you'd probably have to pick a fight like Blackhorn with decent uptime and Method's top guy was doing 48k so at least that number is relatively accurate, but still too high for the average player.
As for MoP, just look at what Method were doing for Garrosh: and this is overcooking it by around 100k, which is quite a lot.
Now, obviously, it depends on when you meant and specific fights, but a cursory glance over end-tier fights tells you the story.
The best players were doing the following (ish):
TBC: 2.5k
WotLK: 14k
Cataclysm: 48k
Mists: 400k
These are the top performers, so it's safe to assume the average player was miles below the numbers quoted.
