Raging Blow still also costs full rage when it is avoided (only supposed to cost 20%), i.e. a dodged BT will only cost 4 rage. It's a newer ability, so there's probably some bugs on oversight. There's a lot of hidden functions for each ability.

On your character sheet you need 102.4%.


On the boss's combat table, it will still read to the game as 100%. It is likely that the paper doll will reflect the total avoidance past 100, and the conversion from block to critical block will happen behind the scenes during actual combat.

I think that we can model Flurry downtime as the chance to have three white non-crits in a row and the chance to have X yellow non crits in a row. Where:

X is the average number of yellow swings during the period of three white swings,
C is crit rate:

E(Flurry uptime) = 1 - (1-C)^3 * (1-C)^X = 1 - (1-C)^(3+X)

This is ignoring per ability crit buff chances (like glyph of Slam)



The unlabeled legend on the right side is supposed to identify each line by a haste value. The band of different values for a given crit percentage represents haste values from 0 to 90%. I made some assumptions to graph this, that Flurry was up 100% (for the purposes of white swing speed,) and that there is one yellow swing per second. So IRL the left part of the graph will be a bid higher (but barely, I think, because crit is clearly the dominant term in the function.)

Notably, at low values of crit 5% crit provides a lot of haste due to increased flurry uptime.

Edit: added the last three sentences, clarified stuff.

Am I interpreting those coloured lines properly to see that haste is reducing flurry uptime?

EDIT: I guess that makes sense as your Yellows Per Second aren't increasing with the haste.
