How did you get that value? At any HZ the ratio should be around 1:10
(+- rounding error).

"Slightly bigger"??? You're joking, right?
Especially the user levels are doing something completely different now, 
which may break user expectation. While the user couldn't expect anything 
precise, it's still a big difference whether a process at nice 5 gets 75% 
of the time or only 30%.
