It would probably do an even better job. The vertical posts aren’t exactly stiff, as can be seen here: Feedback on calibration and resulting dimensional accuracy - #21 by hendrik
I’d like to replace them with something stiffer (even just a skin on both sides would help) and make them as wide as possible at the bottom. Below the belt level in each quadrant you can make the posts as wide as you like to improve stiffness in y-direction.
