Potential patch notes error?

While reading the patch notes I noticed something that doesn't make sense in the update to Fizz.

GUPPY SHARK If Chum the Waters travels less than 455 units, it will summon a Guppy Shark after 2 seconds. GUPPY AREA OF EFFECT 200 DAMAGE 150/250/350 (+0.6 ability power) SLOW 40% KNOCKBACK 150

NORMAL SHARK If Chum the Waters travels between 455 and 910 units, it will summon a normal (but still terrifying) shark. NORMAL AREA OF EFFECT 325 DAMAGE 225/325/425 (+0.8 ability power) SLOW 60% KNOCKBACK 250

GIGALODON SHARK If Chum the Waters has traveled at least 910 units, it will summon a massive Gigalodon Shark GIGA AREA OF EFFECT 450 DAMAGE 300/400/500 (+1.2 ability power) SLOW 80% KNOCKBACK 350

Ok, so the minimum damage is 150. If the fish travels a moderate distance the damage is 150 x 1.5 (225). If the fish travels a long distance the damage is 150 x 2.0 (300).

But when Fizz gets to level 11: The minimum damage is 250. If the fish travels a moderate distance the damage is 250 x 1.5 (375). NOT 325 If the fish travels a long distance the damage is 250 x 2.0 (500). NOT 400

The same thing happens at level 16. It appears as though instead of multiplying the minimum value by 1.5 and 2.0, instead they added by 100 each time. 150/300 = 1/2 but 350/500 =/= 1/2 The AP ratio's don't make any sense to me at all. With the numbers how they are, a long range fish is more valuable at level 6 than at level 11 or 16.
