If on jan 31st u had less than 389 favors then you were not on it. The number is the lowest favors you can have to be in that bracket.
@Unknown, if you're on mobile, open your profile and scroll to the bottom and you'll see how many Favors you have. If on PC, go to the "Misc" section of the supplies tab and see how many Favors you have. The LB for today isn't updated yet, but you just sort of compare your favor amount to those on the LB, as you can imagine.
