The general rule is that 1000IU of D3 for every 10 pts you need to raise to.
The real new normal is 50 in the blood test. But your 41 is a good level... and it seemed to work for you as well. Why not stay at your dose that gave that level to you?
If you get alot of sun, enough to tan well, in summer, you can cut back then. But in winter I think most people in cold climates could use a good dose daily.
