Move object at the same speed as average speed of players

Side scrolling beat 'm up with max 4 players.
Focus the camera on the center of players doesn’t fit in my design.

I want to move the camera on Y based on the averaged speed along Y vector of the players. I got the code that gets the average speed based on total players working fine.
How do I now move the camera with that speed?
I tried vinterp with setactorlocation and I tried multiplying a deltalocation on a addactorlocaloffset node with the result of the speed divided by the player count. I get close but the camera speed is inconsistent, it should allways be moving exactly as fast the center midpoint between the players is moving.

I’m guessing there is a node somewhere that allows me to move an object along a vector at speed X but I can’t find anything that looks likely.
