Movement speed bonus [item] ability levels

[kokon]

I try to change my unit movement speed changing Movement speed bonus levels. From 1 to 8 every 0.25 seconds.
I see that printing GetUnitMoveSpeed() is changing. But I'm not sure I observe the change visually.
1. Can it be that Movement speed bonus [item] levels applied to a unit does not work
2. Can it be that GetUnitMoveSpeed shows some speed, but the unit speed is different irl?

There are some item abilities that don't really work with increasing their levels, it's a bit of a case by case scenario so I wouldn't be surprised if it was the case, so you'd need to use another way, like separate abilities (+50, +100, +150 etc) or modify the speed via trigger directly

Also with standard constants the maximum speed is 400, and is hard capped at 522
