Of course, but the chart still gives a comparision that is valid. Not to mention that one can spin tires on the rims - but the bottom line is that the higher number of skid spots the less you have to think about any of this.
I'm leaning toward a 43 ring. Right now I converted an old bike resulting in 40x14, but for a variety of reasons I (unfortunately) need to change the cranks, so I'm using this as an opportunity to pick a good size chainring.
I wonder why 48x16 is so oft recommended as it has the worst skid spot? I guess 48 chainrings are more common.
