Can I trust the space-freed numbers Storage Studio shows?
Short answer: Yes. Freed space is measured on your disk, not predicted, and Storage Studio tells you when results fall short of the estimate. Breakdowns are never scaled to look tidy, and unexplained space gets its own line.
Yes — they're measured, not predicted. After a clear-up, Storage Studio reports space genuinely returned to your disk and compares it with what it expected, telling you if it fell short rather than quietly claiming success. Because copying finishes before space comes back, the figure catches up as each item completes, and the screen says so.
When it explains where space went, figures are never scaled to make a total come out neatly, and anything it can't account for is shown as its own line. See What's Using Space.
