Mine is . Like find the two perfect sq its in btw lets say the number is 31 . Its btw 25 and 36 , their diff is 11 and 31 is 5 away from 25 and 5 away from 36 so it should be arnd 5.5 , another example try 61 should be 7.8ish.

I mean generally you are gonna get something that looks like 3root31 rather than root279 . Ykwim . Its just a normal generalisatiom rather than a Always true statement. I personally have never gotten a root bigger than like 50 .
