If in local.cf i have such rules for spamassasin:

use_bayes 1
full BAD_WORD /advertise/
score BAD_WORD 6

So i use both: bayes and my own rules.
Can i in any way set weight for both methods ?

For example set bayes range to: from -100 to +100
(to be relatively much more important than 8 points which could be gaine
by BAD_WOED rule ) ?
