It could also give you a few
extra valuable seconds of power in the case of an oil
loss.

There is an
additional advantage. If you happen to lose oil pressure,
(even with a 2 piece centre bearing crank), the rotor has a
natural tendency to cock on the stationary gear due to lack of the oil
film on the crank journals. If you have clearanced the rotor
tips, then there is less likelihood that the corner & side
seals will be swaged into their grooves. In reality, loss
of oil pressure is usually catastrophic anyway, and the rotor
usually needs to be replaced as the raised lands (the rotor gear and
the land on the opposite side sit proud of the actual rotor faces)
usually cop a hiding and end up cleaning up below
spec.
