I think it's dead-on. The middle ring on the front and the middle sprocket on the cassette (7-speed) results in a perfectly straight chain.
Context: this bike originally came with a 5-speed freewheel and hub spaced to 120mm if I recall correctly, and I currently have a 7-speed cassette/hub spaced to 130mm in the frame.
