Sorry, sorry. Anyway yes to a degree, but your dynamic range would be scuffed and you'd still make more mistakes. Like by analogy, if I'm a carpenter and I try to build a set of cabinets with a ruler that only has 1 centimeter markings and no millimeters anymore, they're going to be way shittier and not line up quite right ans not close fully, etc., even though I'm consistently using the same rulers throughout. The lower precision will make the answers float around further from the true mark.

It will always just add more and more errors.

edit: or not an analogy, just the extreme version of this actual issue would be full colorblindness, i.e. grayscale. You could still paint in color but you'd have to guess which color. Partial points along that continuum will be some way in between "the right color" and "guessing"
