The cape would also massively inflate numbers on the second boss as well, as the imps spawn every 30 seconds.
Tyrannical 12 bosses last about 2 minutes, or slightly more depending on the boss. That's 100% uptime on prolonged potions, and on boss 1 and 3 you're going to have a pretty large uptime on lust (even higher on the first boss considering he dies shortly after hitting 25%).
Keep in mind also that in CoS you can get 10% more haste, 10% more crit or a flat 10% more damage.
Maybe it's high I don't know, but CoS has buffs which inflate numbers a bit. His range was 450-500k, which while a lot is a lot a big range. If he was doing the low end on the last boss (450k) and they had the 10% damage buff, his realistic damage on any other encounter would barely be above 400k, which sounds a lot better.
