No, it is generally considered a flawed and outdated method. Most linguists reject its core assumption of a constant lexical replacement rate.

No. It provides rough estimates with large margins of error and is highly sensitive to the data and constants used, making its results unreliable.
While no direct statistical 'replacement' exists, most historical linguists now rely on the comparative method, archaeological evidence, and DNA studies to correlate linguistic changes with other historical data.
