AMBER: X-CA-CT-X dih. FF param ?

Dear Amber Users,

I have a question about a dihedral force field parameter in parm99 and gaff:
X-CA-CT-X has a IDIVF=6 and PK=0 phase = 0

 Why PK = 0 ?

This seems more or less general for FF param having IDIVF=6 ?
Is there a particular reason for that ?

I fitted the "CA-CA-CA-NT" FF param to "Eqm-Emm(non-bond)" and PK is really
different from 0...

Thanks, regards, Francois
