HaKu is on a distinguished road
For example there r two schemes

scheme 1: the convegence rate for u velocity is changing from 3.44 to 4.53 as the grid is increased

scheme 2: the convergence rate for u velocity is changing from 3.44 to 2.32 as the grid is increased

both schemes are using 5th order scheme to calculate the velocities...

which scheme is behaving better??? it is also to mention that the error in the second scheme is lesser as compared to the first scheme...

kind regards
