This is a mess.  
o  Terminology is incorrect and ambiguous--NetBackup does not have
an Incremental; more precisely, there are two.  We can guess that
you meant diffs only because your example shows cincs.  

o  If you have diff and cinc schedules and the policy type is
Windows-NT, you must specify whether the incrementals are based on
archive bit or ctime.

o  You did not specify whether the schedules are frequency- or
calendar-based; It can make a difference, and if both are used, is
incorrect usage.

o  If frequency-based, you did not specify the frequency; the answer
is different depending on the frequency values.

o  You did not specify retention; the answer is different depending
on the retention value.

Assuming you have reasonable values (frequency, windows, ctime,
retention)

Neither.  Read the NetBackup Administrator's Guide, Volume 1 |
Policies | Schedule attributes tab | Types of backup | Differential
incremental backup

Yes.
