Do I have to play every day to not drop back to diamond from master?

I'm just about to (hopefully) reach Master, and I read about [ranked decay]( It says that Master+ players will lose 100 LP every day when they don't have games in their "bank", and you lose one game from your bank each day. So essentially I have to play one game per day, on average? I usually only play on weekends, and around ~3 games per day, so that would leave me at -1 bank each week. Does this mean I'll just instantly drop back to diamond from master?
