What used to look like this:
            desk_pokemonwiki.skp    9.38ms -> 9.76ms    1x
                 tabl_pravda.skp     237us ->  241us    1x
          desk_css3gradients.skp     249us ->  254us    1x
            ....
               desk_fontwipe.skp    39.6us -> 38.7us    0.98x
                   tabl_digg.skp     922us ->  893us    0.97x
                  tabl_gmail.skp    20.7us ->   20us    0.96x

Now will print more like this:

            desk_pokemonwiki.skp    9.38ms -> 9.76ms    1.04x
                 tabl_pravda.skp     237us ->  241us    1.02x
          desk_css3gradients.skp     249us ->  254us    1.02x
            ....
               desk_fontwipe.skp    39.6us -> 38.7us    0.98x
                   tabl_digg.skp     922us ->  893us    0.97x
                  tabl_gmail.skp    20.7us ->   20us    0.96x
