Not really. One of the nice things about designing systems in CAD (like we did with this system), is that things like belt wrap can be calculated to tenths of a degree. With that kind of information, things like load profiles can be modeled and calculated. Granted, there are always variables that cannot be accounted for. That's why we do testing and verification in addition to design work.
By the way, how were you able to determine that there is less than 50% belt wrap on those pulleys? I mean, I know Sam takes great pictures and all, but I'm not seeing less than 50% wrap in the pictures myself.
