Don't start a new line every time you start a new sentence.
Flurry uptime is not a good metric to evaluate Haste with.
Haste does not cause any change in flurry behavior concerning white hits.
Yellow hits have higher chance to crit, but the output rate of yellow hits is limited by global cooldown, higher haste allows you to consume more flurry charges between yellow hits.
But realistically that is a marginal side-effect of haste in all but extreme situations.
Even if your flurry uptime decreases theres no negative interactions between haste and flurry, as crit increases the changes in flurry uptime caused by haste decreases.
