Generally you shouldn't really care about the exact positions or areas of objects, or at least i don't. The only time I did was Areas of banks.
I rely more on the locations of Rs2Objects or Entitles instead since those objects can be easily interacted with using the api, and that is likely what you're going to do anyway. Your dynamic instance is still going to have common Rs2Objects/Entities right, why not use those to navigate instead?
