Wrong (the code)
Worst Cum Best Cum Worst Points Best Points
1 0.0 0.0000 258.0 162.0
2 0.0 0.6000 141.0 162.7
3 1.0 0.9000 206.4 162.4
4 1.3 1.6091 125.8 162.0
5 2.1 1.6299 140.5 162.0
Goal: how?
CUM Points
Worst Best Worst Best
1 0.0 0.0000 258.0 162.0
2 0.0 0.6000 141.0 162.7
3 1.0 0.9000 206.4 162.4
4 1.3 1.6091 125.8 162.0
5 2.1 1.6299 140.5 162.0
Trial 1: fail with many data.frames

It is wrong because it replaces the inner headers with higher-level header nb "NA" vals.
