how does grace work?
so is it like a time period where i can lose all the games i want and not get demoted or is it like a specific number of games i can lose without getting demoted (if so, how many grace games are there?)?

I think it's based on your MMR, but I may be wrong.
After being promoted into a new Division, you get 3 games of demotion protection.
For being Promoted into a Tier, it's 10 games (3 for Master).
Beyond that there is some sort of rule with MMR that prevents you from dropping down if it's not too low, but there is no exact source for this so you'd have to make some assumptions. I hear you can't drop out of a Tier unless your MMR is at least 1 full tier lower (I've never had the chance or want to test it).
