I'm sorry but you don't seem to understand the formula or what I was saying. My whole point was that they are at best equally efficient according to Fitts's law, and your diagram only confirms that. However, Ross has claimed both ways are worse in difference situations, which is a contraction. Now I'm not claiming this was intentional deception and I may be wrong about the reason behind it, but none of this changes the fact the two criticisms are not only contradictory but untrue according to Fitts's law. At least in the way he presented them.
