Female Heavyweight Limits / Undisputed/Lineal/Ring Mag Champion?

[danundisputed]

Hi

What are the exact Female Heavyweight Limits?
I've noticed that the limits differ between WBA, WBC, WBO & IBF,
so what's the deal?

Acoording to the 4 Majot bodies ratings it says:
WBA 175 lbs+
WBC 168.1 lbs+
WBO 201 lbs+
IBF 200 lbs+

That's kinda confusing, esspecially now since Shields is the Undisputed Champ.

Apart of the weight limits, the questions is:
Is Claressa Shields now also the Lineal Female Heavyweight Champion and/or the Ring Magazine Female Heavyweight Champion?

I'm looking forward to get this cleared, thx in advance
