In other words, sub-centimeter movements aren't synced until they eventually exceeded an actual centimeter.\n\nDepending on how important the object is, a precision of 0.01-0.10 (1-10 cm) is recommended.\n\nFor example, even a 1cm precision combined with delta compression cuts the Benchmark demo's bandwidth in half, compared to sending every tiny change.")]
