@M_Courtney, you create your own pricing formula, therefore you can assign any values to your work.
These records are strictly for your use, and you must determine if tracking the different values of your work would be worth any associated bookkeeping costs of tracking (extra time?). You must decide if accuracy in valuing your skills for determining your prices will help you achieve your goals.
A variety of solutions have already been suggested for when your pricing exceeds what your market will pay:
increase the perceived value of your work
serve a different market
decrease your remuneration
