What is Real Range for Teslas?

Trying to understand the "real range" info on a vehicle report?

Real range is the typical range we observe for an average Tesla of the same model, battery pack size and a similar age and odometer based on the Recurrent community’s real world driving and charging habits. It is a mix of city and highway driving in various terrains and temperatures. This value will differ from the original EPA range estimate, since the EPA estimate does not account for temperature differences and allows manufacturers to apply their own adjustments. Tesla Real Range is what typically happens in day-to-day driving based on over 360,000 discharge sessions, covering over 20M miles, across nearly 10,000 Teslas.
