What is the playoff qualification scenario with 4 IPL 2020 league matches left?

There won't be any dead rubbers in IPL 2020. DC-RCB match will be a virtual quarter-final for a spot in Qualifier 1. However, the loser of that match may also qualify for playoffs depending on other results. SRH can qualify for the playoffs if they beat MI. Two teams will qualify with 14 points, which has happened only once previously.
