When I pulled down the steps to the attic, the temperature would fall very rapidly - I wish I would have thought of the tennis ball trick. I guess it shows that the soffit vents weren’t enough.
When one combines soffit vents with ridge venting, the attic temp pretty much remains at ambient outside temp. That has been my experience. My home is oriented East/West and thus the prevailing winds through the ridge vent serves me very well.
