Just noticed something that seems a bit out of whack, maybe its just me.
On 23andme I see a mother daughter match probably 4th cousin-ish. The numbers don't seem to work out compared with GEDmatch.
Mother .3% on 23andme 33.4 cM on GEDmatch
Daughter .26% on 23andme 21.9 cM on GEDmatch

I seen two formulas to convert cM to % and the other way. These don't work out the way I think they should. The daughter seems to work out close but the mother is way off.

I suspose they are figured differently or is one more acurate than the other?

I know at 4th cousin I am spliting hairs but just bugs me.

Any thoughts?
Thanks
