Description
Seems I can't find a way to add custom format variables, for example, for the image exposure value (not the 'bias') calculated by the formula $$\log_2{(100N^2/(\rm{ISO}\cdot S))}$$, I could add a variable called $(EV_AT_ISO100) and use it in lighttable tooltip/overlay text formatting textbox. Or, can I modify the overlay text directly in lua scripts?

Research direction
The issue names no files, tests, or entry points. First identify where lighttable tooltip and overlay text formatting are implemented, then determine how custom variables would be defined and evaluated; done means a documented variable can expose the requested exposure value in both formatting contexts.
