Ancestral Family Tree DNA Testing / Re: DNA ethnicity logic check / Unexpected result

Ooooh, it's been a while, but I thought I'd come back to this again.
The girl who I initially matched to we now think is my 1st cousin once removed, as her mother has subsequently taken a test and has come back as an even closer match which would rather suggest her mother is my first cousin. In turn, her grandmother has now agreed to do a test to determine our relationship; as if she is my aunt, then we know my biological father must be one of her own brothers... it's just not easy to know which one. Several of them are dead, and the one who is alive would not be interested in finding out.
But what I wanted to check is if anyone knew much about the accuracy of MyHeritage's relationship suggestions as they offer a 'range', rather than a specific relationship? I'm going to use initials to protect identities, but the relationships I know about now are:
BC - first girl I matched with, we share 543 CMs. The suggestion is 1C1R, Great Niece, or 2nd Cousin
PW - mother of the girl I matched with, we share 1,130 CMs. The suggestion is 1C, Great Aunt, Great-grandmother or great-granddaughter.
Would there be any way for me to know definitively which of those suggestions is correct?
For PW I immediately ruled out her being my great-granddaughter or grandmother because I don't have kids and she and I are only about 12 years apart in age, so that would leave a cousin or a great-aunt. Is there any way to actually know?
When PW's mother takes a test: If she is my aunt: Would that give a 100% definitive result? Or would it still provide a range of suggestions?
This is all doing my head in after so many months. All I want is definitive answers.
