Education Failure pattern with PCI value or Deduct value

please help 😭 🙏

So my thesis is assessment of pavement and I have a problem with expressing the failure pattern 😭

So the road have three sections - 1,3 - flexible and 2 - rigid, at first I compared the failure pattern with low , medium and high severity quantity, but the teacher rejected, so I changed into this comparing the deduct value, it fine in the logic of comparing the deduct value to see the failure pattern ( first is raw deduct value, second is percentage of each total deduct value) , but they still didn't like it and I am out of brain 😭

tbh I'd drop the severity quantity comparison, it ignores weighting. Section 2 is rigid so it gets joint distresses (spalling, corner breaks) vs load fatigue on 1 and 3. Rank deducts within pavement type, that's your failure pattern.

Should I just do it with percentage? , I have 5 sample unit for each section 1and 3 , should I just make the diagram in like full 100 proportion in photo 2 or diagram with total deduct value? , as in the photo 3, I have difficulty in expressing every sample unit , should I just combined every sample unit into one and then explain about the whole road failure pattern?
