Ice ball damage scaling does not match Java Edition

Steps to Reproduce:

1. Spawn any mob

2. Hit it with ice balls until it dies

3. Do the same in Java Edition

Observed Results:
Despite having a lower power multiplier (1.3 as opposed to Java’s 1.395), you will always need less ice balls to kill a mob. The velocity of the ball also seems to have a smaller impact on the damage.

Expected Results:
The calculated damage is the same, with the power multiplier also matching Java.

Notes: The values used for the gravity, inertia and initial power match Java Edition, and the trajectory seems similar, so the physics are unlikely to be the culprit.
