What do they say, "25% you can get close to a match and 25% you can't get a match". You could try another swatch with CMYK: C=0 M=73 Y=100 K=0 to see if that is any closer than Mike's although I would try Mike's first as that's what used as the standard conversion. I used PS to get the above value but unless you print the two together using the correct links. Also we had a trick in the newspaper when I worked there was to increase the sat. by duplicating the swatch shape and doing a "colour multiply" to get rid of washed out look. You may have to reduce the opacity very slightly when doing this trick but if you have a desktop CMYK laser and use your Pantone book you can view each of them alongside each other.
