Also known as premature optimization. You had to literally invent new dataset just to show there is a difference. You are inventing problems, stop doing that!
Sometimes that is how useful jumps are made. Maybe someone will come along with a problem and the data they have just happens to have similar properties.
Rather than premature optimisation this sort of thing is pre-emptive research - better to do it now than when you hit a performance problem and need the solution PDQ. Many useful things have come out of what started as “I wonder what if …?” playing.
