 As for your reference, and configured as defaults, the *Berkeley LCS Tutorials* used ``RK4`` for advection.
-The velocity fields were interpolated by ``tricubic-FL``, originating from [Lekien2005]_, which has higher performance by solving a 64*64 linear system using the function values, gradients, and mixed partial derivatives at its eight corners, which is in future plan for ``Py3DFTLE`` with high priority.
+The velocity fields were interpolated with ``tricubic-FL`` by them, originating from [Lekien2005]_, which has higher performance by solving a 64*64 linear system using the function values, gradients, and mixed partial derivatives at its eight corners, which is in future development plan for ``Py3DFTLE`` with high priority.
 Although not detailed, ``grad_order=2`` was employed by them from the equation, supposing the mesh is sufficiently refined.
-Please always notice that, although providing much better numerical precision and looks cool in papers, high-order methods could be resource-consuming, even hundreds of times.
