Mel Q is not dodgeable (math)

If you're frustrated like I am with this champ, don't worry. It's not your fault you can't dodge Mel Q. Riot designed her so you can't.

Mel Q takes 0.42 seconds to hit its target (0.25s cast + 0.17s travel). With a radius of 280 units, it is not possible to dodge this ability unless its caster misses. Math below:

Most champions have a hitbox size of 65 units. Almost all champions have a base movement speed between 325 and 345 units. Let's take the average to be 335 units.

Since Mel Q is an edge skillshot, for a champion to dodge they must travel 172.5 (=280/2+65/2) units in 0.42 seconds. This equates to a required movement speed of 411.

...And that's before reaction time. Reaction time for the average gamer is 0.20-0.25s, with professional gamers being 0.11-0.17s. Assuming you are literally Faker with a fastest measured 0.11s reaction time, you would need 556 movement speed to dodge a centered Mel Q. For an average player, you need a whopping 784 movement speed.

Here is the guaranteed hit range of Mel Q: https://imgur.com/a/CYuGWGb

Green is vs. no boots, yellow is vs. t2 boots. If Mel presses Q anywhere in this radius, at least 1 missile is guaranteed to hit an average player.

In other terms, if the average player reacts immediately to Mel's Q animation start, they are still expected to get hit by 42%/33% (no boots/boots) of the spell. If the average player reacts to Mel's Q damage, they are expected to get hit by 100%/93% of the spell.

Simply put, if you're getting hit by Mel Q repeatedly, it's not because you're bad at dodging, it's because Riot made the skillshot a guaranteed hit as long as your opponent has hands.

p.s. Mel Q is 280 range because its a 220 range projectile + 60 range spread, which makes it ~1.5x the size of Xerath R. The 60 range spread does not have a meaningful effect on any above calculations, other than the guaranteed hit range goes down by a tiny bit (yellow becomes without boots guaranteed hit range) if you are ignoring the spread.
