I posed the very same question on more than one occasion. As I worked with Mark Glickman on a few projects, and he created the most-recent version of the system for the United States Chess Federation, I assured Fencer his rating calculations were not correct.

The BKR for the provisional period is off by orders of magnitude. The handling of draws is also incorrect.

Fencer uses the "parallel" Glicko calculation for
"many results" being rated at the same time during the provisional period, and Mark Glickman later retracted this method.

If you are interested in a high BKR, all you have to do is win a few games against strong opponents during your provision BKR stage, then just gets draws once you have 25+ games. Your rating will never go down.

This is not the way the rest of the world operates.

Lower rated players will gain points when drawing a higher rated opponent, and the higher rated player would lose points if drawing a lower rated one.

I have not seen an example of that here.
