new try, times are jumping
rand10 = Length = 38.870136, time in seconds = 0.000913
rand100 = Length = 1888.492776, time in seconds = 0.016582
rand1000 = Length = 82430.569174, time in seconds = 2.645039
rand10000 = Length = 3707449.504854, time in seconds = 3.827995, was 3731327.006039
arx command is 'doit '
edit: changed, the larger the set, the less optimal, otherwise times shoot through the roof lol
