The pricing display options differ in which rate your guests see.
Base Nightly Rate shows the static base rate.
Lowest Price displays a highly competitive rate. It can sometimes set unrealistic expectations for guests if that rate is rarely available.
Average Price offers a more realistic baseline. It can be skewed higher if there are significant pricing spikes in your future calendar.
For both Lowest Price and Average Price, you can restrict the calculation to a specific forward-looking window. This gives you better control and filters out extreme outliers.
