Yeah, that's some kind of difference, but points are adjusted accordingly for 1 off, 2 match series, 3 match series and 5 match series with a max of 120 points for the series whether it's 2 match series or 5 match series.
For e.g. if there are 2 matches to be played in a series, then each will have a max of 60 points. If there are 5 matches, then each will have 24 points only per match.
This was as per the initial setup, but they couldn't achieve that because of Corona and have to rely on Percentage of Points as agreed by ICC .
It may not be a 100% viable one, but we might see some updated rules for the points scoring.
