I am currently playing at low stakes. Since i do not like and think it is okay to use very simple preflop range, i just use simple preflop range(it is based on GTO but far different from actual GTO preflop range)

This is my BB defense range vs BTN open.

When I study by solver, do I need to input my own range?(which is very simple, either 100% or 0% of hand) or somewhat close to GTO range?(somewhat complicated, some hands are in the range about 23% or something)
I know that when I move up, I need to have more solid and complicated preflop range, but at least now, I don't think I can handle with complicated preflop range.
