Auto Accident/Personal Injury....Am I on the right track

I was involved in an auto accident a few months ago and the at fault driver admitted fault. No tickets were issued, but my vehicle sustained $9,800 in damages. My Land Rover was in the body shop for almost 2 months because the parts took a long time to arrive and it sustained suspension damage. I will be taking my vehcile to the Land Rover dealership next week to have them appraise the value of my car post body shop repair. I plan to seek 3rd party diminished value.

My medical bills total $5300 (medpay--no subrogration). I was treated for a muscle strain in my right arm, headaches & muscle spasms in my back and neck and referred to physical therapy by my medical doctor. I've been on prescription pain medicine for the last 2.5 months. My lost wages from work total $951.00.

I'm done treating and I am trying to figure out how to calculate the value of my claim? I found a website that uses The BASE (Baldyga Auto Accident Settlement Evaluation) Formula. It adds up your medical bills, lost wages, rental car, and auto repair bill and uses these figures to place a value on your claim.
Here are my figures:
Medical Bills $5300; Rental Car $2600; Auto Repair: $9800; Lost Wages: $951

I'm certain this is not accurate because its saying my claim is worth between $27,710- $45,447
