There is only a set number of Proc Status’, the rest are combinations of the status’.
So for example 16512
Take the closest listed status, 16384, and subtract it from the displayed one.
That gives you 128.
So a Proc Status of 16512 means
128 RDW Sent
16384 cost adjusted (set by PROCs when cost was adjusted by MPROCIN)
