I also misinterpreted the phrase “timelines can be frame independent” as the update exec pin wouldn’t be dependent on tick interval. Just a few weeks ago learned that this was not the case from a distinguished gentleman.
To make your timeline frame independent, you gotta plug the value of it’s float track either into the Alpha pin of a Lerp node, or the Delta Time pin of an interp node (finterp, vinterp, rinterp, tinterp). And also be careful to not interpolate between changing values, except for the Current pin of an interp node
