I don't know if this exists already or if I could use an app if it does exist
Or if I can explain what I mean
But if there is a chart which you can put cm numbers of your own cm matches top ones at top then along top:
child /sibling/ cousin half cousin / parent aunt / 1c1r )// 2c / 2c1r /grandfather
And fill in cm amounts of those that match you and where known those that match each other
For example along top I would have mother
And first row down would also have her top corner box our amount
Next row I'd put my cus and how he matches me and how he matches her in next column
Leaving a few rows blank for future testess or people who's relationship to each other and me unknown
Then we'd also need an algorithm ? Gadget thing
To show if I match a by X amount
And mother matche z amount and 1st cousin matches each of us by y amount
Surely the painter DNA range narrows every time you combine another known relationship
If you are as confused as me please comment
If you can number crunch please suggest solutions
Here is a link to charts I've put side by side
I will add two people who appear as first cousin relationship to each other and how they compare to my closer family
