recent drastic changes in u.s. ratings for my boxer Johnnie Langston

[computerrank]

Boxrec ratings changed around year's turn.

Too many boxers got too many points against opponents with unsufficient recent success. Now boxers will get less points for defeating underachieving opponents. The general level of rating points dropped by about 50 percent.

This improved the winner prediction ability of Boxrec ratings by about 1.5 percent points up to 83.5 percent.

Johnnie Langston so got much less points now for his opponents, as his opponents themselves are now rated much lower. than before.
