+Pay the Scottish Carer Supplement for each award week in which Carer Support Payment is payable, up to 52 a year, counting the weeks from the larger of the payment and the entitlement before the overlapping-benefit reduction, so a carer paid 13 weeks of Carer Support Payment after moving to England gets £152.10 of supplement in 2026-27 rather than £608.40.

+# Award weeks. SSI 2023/302 reg 14A: "An individual is entitled to Scottish
+# Carer Supplement for each award week in which Carer Support Payment is
+# payable to the individual." In reg 2, "award week" means "a period of 7
+# days beginning on a Sunday and ending on a Saturday". The Scottish Ministers
+# set the weekly rates in reg 16(1) and (1A): Carer Support Payment 86.45 and
+# Scottish Carer Supplement 11.70. Under reg 42(1) and (5), a carer who moves
+# to another part of the United Kingdom keeps Carer Support for 13 weeks from
+# the day they stop being ordinarily resident in Scotland (reg 42(4)). Under
+# reg 42(1A), where the cared-for person dies in that time, the carer keeps it
+# for 12 award weeks after the first day of the award week following the one
+# in which they died, up to 25 weeks and 6 days in all. The move cases below
+# put the move on a Sunday, so they count 13 and 25 complete award weeks, each
+# from a Sunday. A move on any other day spreads the 13 weeks over 14 award
+# weeks. The formula counts the weeks as the larger of
+# carer_support_payment_pre_overlap and carer_support_payment over the weekly
+# Carer Support Payment rate, up to 52, and pays the weekly supplement rate for
+# each where carer_support_payment is positive, and nothing where it is £0.
+#
+# The count differs from the law in these cases, among others; the variable's
+# documentation names each:
+# - an overlapping benefit or earnings that vary within the year;
+# - a supplied part-year payment for a person the model finds eligible in
+#   Scotland;
+# - a supplied payment that an overlapping benefit has reduced, with no amount
+#   before the reduction;
+# - the disable_simulated_benefits reform;
+# - a supplied part-year amount before the reduction, which the model nets
+#   against an overlapping benefit paid all year: 1,123.85 for 13 award weeks
+#   and 2,000 a year of State Pension net to 0, where Social Security
+#   Scotland nets them week by week and pays 623.85 of Carer Support
+#   Payment and 152.10 of supplement;
+# - part weeks, where Social Security Scotland pays a whole weekly supplement
+#   for each award week in which Carer Support Payment is payable.
