Another addendum, i'm not sure i'm getting what's happening here:

If i calculate the average of the time perl took divided by the time ruby took, i get this:

((226/724)+(5.35/16.8)+(3/9)+(2750/3960)+(1120/1368)+(3236/3837)+(30.5/35.8)+(939/618)+(263/135)+(662/214))/10 = 1.07

Which i understand to mean that perl on average took 7% longer.

However if i turn this around i get:

((724/226)+(16.8/5.35)+(9/3)+(3960/2750)+(1368/1120)+(3837/3236)+(35.8/30.5)+(618/939)+(135/263)+(214/662))/10 = 1.58

Which i interpret to mean that Ruby took, on average, 58% longer.

These things contradict and i made some mistake here. Can you clear up what i should've been doing?
