clones falling into position

I have a scene where I want to move clones from up above into the final position. In general this works fine.
I now wanted to add some randomnes to the scene, so I used a random field on top of my linear field set to overlay which works fine, except the clones that are already “activated” don’t move linearly to their final position. They slightly ease into the position which normaly is fine for me but I would like it to more feel like falling into place. I guess there is a technically answer to why they behave in this way. But is there also a way to get the clones into there final position more linearly?
Is there another way to activate them randomly?
I have attached a simplified scene file. Thanks for your help
