I concur!

In fact, unit types in armies probably should not make much difference at all!
Most of them will be marching with their supply trains so will go as slow as a wagon anyway - all cavalry, all yugekitai, or all kisho ninja armies might be able to justify some faster speeds but on roads most armies will be going the same speed, one would think.
