The salary floor is correct; it is now 140% of the TV contract. From the offseason update before the beginning of last season:
As we have mentioned in our last season news post, we are a bit worried about the number of users that have chosen to follow the strategy called “tanking”. Even though the strategy is not very successful, some teams still pursue it and it's frustrating for their fellow league members to see less competing teams. Therefore, we have decided to take some measures. “Tanking” should still be an option and we don't want to eliminate it completely, but from now on, the profit, we predict, won’t be so high. Starting in Season 21, the salary floor will change for the first three divisions. First division salary floor will be 180% of the tv contract, second division will increase to 140% and third division to 100%. The other divisions will remain the same.
