 As a user, I want to know that:
 
 - My buckets represent my real categories of spending, like beer and holidays;
-- My pipes represent how much I want to come in and out of each bucket;
-- Each real transaction I make may be associated with at most one bucket;
-- Buckets have a balance, which represents the amount of money I intend to be
-  free to spend in the real category of spending which that bucket represents;
+- My pipes represent how I want to distribute my incomings and outgoings across
+  my buckets in the future;
+- Each real transaction I have made in the past to be associated with at most
+  one bucket, so that my transactions represent how I have distributed my
+  incomings and outgoings in the past;
+- Buckets have a balance, which summarises both how I want to distribute my
+  incomings and outgoings in the future, and how I have actually distributed
+  them in the past;
 
 so that I can have buckets and pipes which express how I want to distribute, and
 have previously distributed, my incomings and outgoings.
