-The conversion algorithms that calculate the duration are approximate, not exact. Speed is not checked when inserting media on a track that already has speed adjustments so duration will not be corrected in that case. You can not do negative time and you can not play backwards.

When working with edits and the speed auto, if you
+make a "cut" in a section, the speed curve values should not change over the remaining playable edits. It is
+possible to easily add "disjoint" curve points at the boundaries of the edit to preserve the curve shape.
