If the framerate is all that important to you, remember that the tick event is being called once per frame, hence your Dash Frame Count is already the frame count.
To get the number of seconds, create a float variable, and use it as an accumulator, adding in the delta seconds that is passed in to the event tick.
So your Dash Frame Count, now holds the number of frames, the accumulator holds the total time. You can then of course, divide the frame count into the accumulator, to get an average time for each frame. You can as well, keep a high and low value from the delta seconds, or any gradiant there of, so that you can also check to see if the Delta Seconds, is falling close to the median, or to an average etc. No matter what you do, you can get the values that you are looking for, without having to hard code the “60” into that FrameRate to Seconds node.
Hope this helps
