Question about setting?

I have question about current bank roll in setting.
It says need update often. Otherwise it effects the risk level. Question is how often? Daily or weekly?
Do we need to change starting bank roll as well?

I only change my bankroll every one or two weeks and no I never need to change my starting bankroll.

I don’t think it’s that important. If my bankroll goes down then I’ll add to it out of my monthly income and if it goes up then I place bigger bets and risk getting limited.
