In round numbers: pi x 1/2l x 1/2w so...
pi x 6 x 4.5(inches) is approx 85 sq in
pi x 6.125 x 4.625 is approx 89 sq in
I think it's plausible to believe one company 'measured' from the outside loop of the string where the other measured the actual available hitting area INSIDE the hoop.
There is a math error somewhere there... 1/4" = 0.25", that's on every side of the frame, no?
Inside the frame: 6 x 4.5 x 3.14 = 84.8 sqin
Outside string: 6.25 x 4.75 x 3.14 = 93.2 sqin
