MSA. PD and C&R

[casual1]

Thank you. So the DA/IC prepares the C&R, not the AA. That is what I thought.
I have the numbers for the PD from the IC, know the numbers for the Mileage Reimbursement owed. Since the PD is 4 years late, can I put a 25% plus 10% penality on PD based on Code? What would be the correct amount to apply? Then can I apply a 25% penalty for Mileage R. that is over 3 months old, unpaid today? How do I figure future Medical Expenses? Will the DA/IC figure this total out with the AA? Is that a negotiable amount based on the parties? How is this number developed? The MSA is for 20K. Can I assume this is for Future Medical? I would think so, just want to concur.
Im trying to come up with a total amount, a number that I will agree on. Can you help me figure this out based on my assumptions. Are my assumptions correct?
