Loose objects can come from three sources: worktree (git-hash-object and friends), git-unpack-objects and unreachable objects in packs released back by git-repack. The last one could be a result of a branch deletion like you said. Depending on the branch size, you could release back a large amount of objects in loose form at the same time. This really skews my "create time distributed equally" model and the new estimation in too_many_objects() probably won't help you much either. If only we have a way to count all these objects as "one"... but putting these back in a pack hurts obj lookup performance... -- Duy
