Helps you calibrate how far to push motion beyond realism so it actually reads on screen. The core insight is that photographic accuracy usually feels dead in animation because the camera loses dimension and feedback. It breaks down exaggeration levels from subtle (1.1x for corporate work) to theatrical (2x+ for cartoons) and what to push: poses, timing, spacing, arcs. The restraint paradox is useful: push until it's clearly too much, then pull back 20%. Works across UI micro-interactions, character animation, and game feel. Most valuable for catching that common mistake where motion feels stiff because you're being too literal with physics.
