Knowing the track was changing speed is probably helpful in bias analysis also. It forces you to look at even smaller samples, but if for example you thought there was a strong bias early in the card and then suddenly the races started developing differently, maybe you weren't wrong in your initial analysis. Maybe the track changed. At the very least you can put that info in your notes.
