The best yamaha mechanic in my county and the yamaha book do not agree which way you count the grooves on the needles. He states that from this pic which is attached that 2,5 by the pic is actually 3,5. One other thing is that he says that the nearer the "fat end" of the needle, the richer?

Who's right?
