There should be no delay. By executed another action do you mean the Print String here? Under normal circumstances, it should fire immediately. Is this not what you’re experiencing?
One thing I’d change about your setup is the way you feed Lerp’s A with Get Actor Location - you’re introducing additional interpolation here since you’re also setting this object’s transform in the same frame. It may not matter in this case but it will give you an inconsistent transition.
Consider creating another variable for the start position before the timeline kicks in, the same way you already do it for the Jump Pad location. This way, the animation takes alpha and alpha only into account.
Here’s what I mean:
This unintended interpolation might be source of the perceived delay you’re seeing - in fact, there’s no delay but the fast object is moving imperceptibly slow at the end of the track.
