I'm assuming this was the thread with all the formulas? I think it was pretty interesting. I like the math behind things. I take that type of information with a 'assuming consistenty of material' when its talking about ideal dimensions and all that. I think it's pretty self evident that the math world generally works better than the real world, and the art involved in bow making, and all things, lies in learning to deal with the imperfections and inconsistancies.
