Calculating Flying Height Rate/Time ratio

I currently don't have a use for this, but I would imagine it would be very useful for any spell maker using GUI.

What I've been trying to work out is rate to time ratio of the "Change Units Flying Height" action. What I am asking, is if anyone knows what this ratio is, for example:

If the Height difference between the units current height and the one specified in the "Change Unit Flying Height" action is 300, then at what rate would one set it to change if the target amount of time for the process to take place is 2 seconds.

All I really want is what the ratio is, or if there is a certain equation that would allow one to find the amount of time a process would take if the rate and height difference is known.

This should eventually allow for one to create spells that are visually accurate no matter the conditions.

the ratio means how much fly eight per second. so here will be 150 (300/2sec) in ratio for it to move 300 heights in 2 seconds

Are you saying the rate is how high the unit moves per second?

So.. changing height to 1000, with a rate of 200, would take 5 seconds to reach 1000?

Yes, like t=d/s

5=1000/200

0 = instant.

Ish.
