Spamassassin's Razor scores

Hello together,

I've been using Razor and SpamAssassin quite a while now
using the standard rules distributed with SpamAssassin.

SpamAssassin normally evalutes Razor's spam confidence level
between 51% and 100%. This results in the following score:

RAZOR2_CF_RANGE_51_100=0.5,
RAZOR2_CF_RANGE_E4_51_100=1.5,
RAZOR2_CF_RANGE_E8_51_100=1.5,
RAZOR2_CHECK=0.5

-> 4 points at maximum.

I'm wondering if it would make sense to add additional rules for 95% to 100% 
spam confidence? Is anybody already using a setup like that? Any drawbacks?

Cheers,
Thomas
