I wish there was too. But I don't find tiny short-term fluctuations much of a problem. The difference is negligible in hours/days/weeks. Sometimes Monero does better and sometimes worse at those small time scales so it basically cancels out if you're always doing it.

There are years and months where Monero does better even. All of 2022 it outperformed Bitcoin and May-September of this year it also did better (~6 months)
