Boxing ranking lowered for no reason

[Kpjmanagement]

Keon Johnson from Indianapolis was ranked 44 in the US about a month ago. Currently his ranking has dropped into the 60’s for no apparent reason. Can you please advise.

Thank you.

the ranking forumula/method changed and hence many boxers rankings changed, some went up and some are obviously feeling the sting of going down

I noticed, matchmakes were used to match their boxers with connected boxers, whose defining wins were long past. And so their boxers could win undeserved points.

I now restricted the connected time period for boxers from lifetime to a time period beginning with the first defining result minus a lead_time and ending with the last defining result plus a lag time.
