here's the spread of the massive_intr results (the average 'jitter' of
the second column of the results - lower values are indicating more
stable / more fair massive_intr results, in percentage):

CFS SD
----------------------
10: 0.02 0.55
20: 0.21 0.78
30: 0.26 0.95
40: 0.27 1.46
50: 0.37 1.24
60: 0.37 0.92

but of course i'm primarily interested is the observed difference in
interactivity :-)
