50MHz not enough to run Daytona 2

I've noticed that while playing the Beginner course in Daytona USA 2: Power Edition, occasionally slowdown will occur while drifting around the last corner, sometimes with a few graphical glitches. It gets worse when the car is badly damaged, with slowdown even occurring on other parts of the circuit.

Fortunately, this can be fixed by setting the PowerPC Frequency to 60 MHz, where no slowdown occurs (assuming your CPU is fast enough). It seems 50 MHz is not quite powerful enough to run Daytona 2 at full speed consistently.
