Not bad except they give inaccurate formulae for stripline and microstripline characteristic impedance. Will these inaccurate formulae ever go away? They've been around since the 1970's. When with the trace widths and board thickness then in use the accuracy wasn't too bad. However they are not very useful for modern PCB design.
