First, I made a mistake, I meant Xayah not Kai Sa, nobody and me included build kai sa crit lol. Secondly, you went on a long explanation on the AA animation wind up (that I already know of) which has no real importance when talking dps, only marginally.

Critical strike is fairly easy to understand on its own, statistically speaking for each point of percentage CS, the damage outptut increases by 1%. Now the thing is in this game AS is attached to crit items. Without factoring in the AS, that would mean that one zeal item should be equivalent to 2 BF swords (80 damage) considering the cost, or that you have at least around 230 attack damage. But if we factor AS in a simplified AS formula (assuming no attack delay), no runes or AS growth, you would get for the highest AS on a zeal item, phantom dancer, you would get 0.625 + 0.625 x 45% = 0.9 approximatively, which means 1 AA every 1.1 sec (1/0.9), without AS it would be 1 AA every 1.6 sec.

So imagine you have 100 bast attack damage, you add 80 damage and you do 2 AA in 3.2 sec, you would have 360 damage. Now with the same base damage, but with 30% crit and 45 AS, you have in roughly the same amount of time (3.3 sec) 3 autos one of which is a crit ; 100 + 100 + 130 = 330.

I'm assuming a lot of of unrealistic numbers for this comparison, but those assumptions are largely in favor of the zeal item, and it's still not quite good enough compared to AD. Some champs synergize with crit and AS in their abilities but most of the adc scale with AD.
