Kerning play

Found this on the web and enjoyed a lot:

It was really fun, to see how you compare your kerning abilities with the professionals. Well I presume the actual comparison is done against the results of a kerning algorithm ... At least this is what I would do.
If I think a little I'll say that I am not that happy to be compared and loose to an algorithm but hey ... it happened to other much bigger than me :)
