I really doubt it too, plugging in 60 months and 60" (5') which I'm certain this cow was at the hip, it gives me a frame score of 9.28... an equivalent bull is around FS 7, so apparently the tape measure seems to be approx accurate for bulls, not so much for cows
at 60 months, a cow is pretty mature, yet it lists a differant slaughter weight for the heifer than the cow.. I don't know about that, listing 1362 lbs as heifer weight, which was bang on what she was when we sold her, she was never going to be the 1607 listed as mature weight, but she was a pretty lean machine
Her mother, at about 54" tall, comes up as a 6.1 frame, and 1300 lbs mature weight... I think she's fat enough she might be as high as 1400-1450 if she's got a calf in the belly.. so it's not far off for that... if you go by the tape measure, she'd be a frame 4 though... which I guess is possible considering I don't have a good reference point to go by
by accident i found out a 6" tall cow weighs -1200 lbs
Based on the information I've been given, i'd have to say I like cows to have a frame size between 1 and 9
