Only considering rotation speed for MOND seems like a simplist, poor approximation.
One needs to take into account how wide/large is the galaxy.
Its 3D shape.
And a map of its local main density/sparsity points with estimated masses.
A failure to estimate accurately any of those metrics seems like the issue with this galaxy, not MOND itself.
