The Roe + Venkatakrishnan configuration predicts lower values, which were observed to be sensitive to the limiter coefficient. For example lowering it to 0.025 increases drag above the values obtained with the other two configurations.

### Maximum lift

Roe + van Albada and JST agree well on the maximum lift, and again match the results of other codes.
However JST predicts the flow to remain attached at significantly higher angle-of-attach than expected.
