ZF Speeds with various gearing and rpm

I looked around for something like this for awhile and couldnt find anything so i just mapped it all out myself and figured id share. was trying to find out the right gearing for best gas mileage and also my top speeds at a safe rpm when gas mileage isnt a concern. has zf 42/47 close and wide ranges all calculated with 33 in. tires
