While I'll agree, 25 or so is a good place to set a single pin, I find that with my set-up, I'm dealing with more like 3-4" low when shooting 30yds, withmy 24yd pin. Part of why I personally like a 3 - 5 pin set-up, with pin setting of 24 - 32 - 40 yds or somethingsimilar. A small misjudgement indistance doesn't make as big of a differencewith the pins that close.
