that chart is from last week (10-16) and their MV was released this week
if Inkigayo counted their score based on last week's numbers then HiSuhyun should get full digital mark and a 0 in the sns category because their MV wasnt out yet
if Inkigayo counted their score based on this week's numbers than HiSuhyun should get higher SNS points than Kyuhyun but he should get higher digital score because he did much better than them this week.
what SBS did was count the digital score and sns score from 2 different weeks (which s against the concept of the show) in a way to maximize HiSuhyun's score and make them win. it is rigged.
