joseph: i just punched in the numbers. Could be they are inaccurate and its possible my math is off. Where did I go wrong?
Another thought I had after I wrote that post, there is a concept in Halacha called Miut Hamatzui or significant minority. The most stringent opinion I have seen (like R’ Vaye’s) is that Miut Hamatzui is 10%. Anything less is halachacly insignificant.
