I don't know. I think both systems are easy for the average viewer to understand.
In ordinal judging, when the Lithuanian judge gave skater X a first place ordinal, it meant that the Lithuanian judge thought that skater X gave the best performance. I, the viewer, might have thought that skater Y gave a better performance. OK. But the Lithuanian judge thought that skater X did.
As for the new scoring system, you get points for all the little tricks that you do. When the points are added up, skater X got 154.82 and wins, skater Y got 147.56 and takes second. I, the viewer, might have liked skater Y's performance better, but skater X ended up with more points.
