+## Accubid Reverse Takeoff
+
+I have mixed feelings
+about using negative or "reverse" takeoffs
+in [[accubid|Accubid]].
+
+### Pros
+
+Pros as an alternative to simply changing existing counts.
+
+With more than one revision,
+it quickly becomes difficult to have confidence in count changes.
+
+### Cons
+
+This note specifically concerns using negative quantities
+to cancel out positive for breakdown purposes,
+which I suspect is the only practical purpose for them.
+Net negative quantities cause all kinds of problems.
+There is no link from the positive to the negative,
+so any change to the former must be repeated for the latter.
+
+With more than one revision,
+determining net takeoff quickly becomes unwieldy.
+
+LiveCount "un-reverses" reverse takeoffs
+when adding or deleting from an existing run,
+which is not intuitive or well known.
