 For bills:
+    * gas bills are a mess and more than 4 per year... *SIGH* try this:
+        - if len(bills) > num_ann_bills (effectively too many bills for what we expect)
+        - normalise by looping over *EVERY* year of bills
+        - for each bill in yr:
+            - pb=find_prev_bill( bill )...
+            - calc days between pb and bill to get daily cost
+            - work out qtr() and take # days from bill in Qtr X and add it to Q[X]
+            - if # days i X+1 add those to Q[X+1]
+        - then need to be careful when working out totals/growth to use Q[...] not bill['year']
     * growth for internet/monthly is a bit skewed.... Really think min/avg/max might need to be smarter
         - at least max, its 114-134 BUT, not in 1 year, really that changed from 2022 to 2025, so 3 years... (or max = 18% over 3 years, or 6%)
         -- so ann_growth_avg or max needs to factor in years of same prices
