Amusing to hear Crofty at SKY say things like that, as if we would be all confused if he had just said 7 hundredths. It has to be specified that it is 7 ONE hundredths. (could it be two?)
I think it’s just to be precise, so that no stickler misunderstands seven hundredths (seven one hundredths as in 7/100) to be 1/700 (one seven hundredths).
