This post on GT Planet explains the numbers: https://www.gtplanet.net/forum/threads/chart-of-the-gran-turismo-sport-fia-points-system.390941/
Its from GTS but it was the same numbers from GT7, until the increased max DR.
I haven't seem a chart for the new points (150K DR) yet, but we know the formula, so it's just a matter creating a new chart with the new values.
