Light Strike projectile chance to hit

Does anyone know how exactly are the LS projectile chances to hit rolled?

Wiki says:

Cannot Miss: This applies only to the projectiles launched after you initiated the strike. Swinging in enemies' general direction will result in projectiles with a hit/miss chance equal to that of the skill itself. Projectiles that miss will be dissipated without doing damage.

Does this mean if I have 90% chance to hit with LS, the game rolls the first check and if it hits, the projectiles inherit this 90% chance to hit?

Meaning, if I had tooltip display of 90% chance to hit, does this mean the projectiles have 81% chance to hit, when shift spamming the skill from a distance?

It means if you smack something with the melee part and hit or miss, the projectiles will inherit the result. If you just fire the projectiles in a direction like a bow attack, it will behave like a bow attack. In both cases you have 90% chance to hit a specific target.

Ok, cool, thanks.

Of course there are ways to take advantage of this behavior, like attacking a white monster to get 100% projectile hit chance vs. an evasive blue or similar.
