I would not set 2nd axis this way without thorough explanation on why it's a better way. Iwould be very interested to see why they think this is better. Until then, setting w/ using the string as you Y plane has always worked for me out to 60 yards. This year I plan to shoot a bit of field archery, so I may be able to test out to 90 meters too.

I would love to see what Len has to say about all this.
