SR5 Combat movement, ... aka teleportation? Options

[CeeJay]

I'm trying to understand how combat movement works under the new rules... and somehow I'm unable to answer these simple questions:

Let's say I'm a human with Agi 5 and an Ini score of 25 (so I will most likely get 3 passes this turn). I want to move this combat turn from one place to another. The difference is 20 m, so I will need my full run rate to cover that distance.

When will I arrive at my target destination? At the end of the turn or at the end of my first pass? Or sometime in between?
How much distance can I cover in one Initiative pass? My full movement rate?

It looks like combat movement is no longer divided by the number of Ini passes... which is understandable, given that you don't know how many passes you will get at the beginning of a combat turn.
But that leads to the effect, that I can use my full movement rate in just one pass, doesn't it? So in the example above I could cover the 20 m in just one pass out of my three, thereby moving with a speed of 20m/s?
And then I would be stuck at my target destination for the next two passes, because I allready used my allowed movement rate? Well, technically I could sprint to move some extra meters, but that's about it?

Am I getting this right or where is my mistake?
