     - something to do with missing year of data in quarterly bills - still an issue
 
 * if change a bill (like Amazon), then its future estimates don't update
+    - recalc does fix, so a simple delete future bills for this bill type and
+      re-estiate will do it, BUT, its a simple POST now...
+      I think a re-write of functions in bills may be needed, so that we can
+      pull out future estimates based on growth (that may need to change due to
+      this changed amount), etc.
+    - also occurs if we delete a bill
+    -- but on the +ve side, changing growth toggle, resets future bills - 
+        so can call UseGrowth( bt_id )
+        SO only missing bit would be to recalculate growth based on existing
+        bills for this bill type.... SO, may not need to redo code everywhere,
+        but should consider it anyway
