To back up my previous claim I made a small crude excel file, simply checking how many % of the guilds that killed boss N killed boss N+1.
The results was interesting.
What these colmuns show is:
Column 1: How many guilds have said progress
Column 2: How many guilds that are wiping on a boss in comparison to people that killed it. (in %)
Column 3: Which boss/progress level
1200 --- Boss 1
1000 20 Boss 2
The 20 means that 20% of the amount of guilds that killed boss 2 is wiping on boss 2.
What we can clearly see is that the biggest "gap" is in heroics. Especially early / late heroics. The gap in normal is barely non existant. The only reason that Jin'Rokh N and the first 3 normal bosses is ranked so high is because of all the ghost guilds and pugs and on raiding guilds inflating the results. In reality they should be lower if you would seed out the inactive guilds / guild migrations / pugs / non raiding guilds.
Quite undeniable that the normal to heroic gap is larger than the gap entering normals.
