A weekly budget or a daily one?

Weekly, if what matters is not passing the month’s cap and a quiet day can leave the rest for the gap. Daily, if one bad day must not eat the money for the rest. Write the week’s cap on paper. If a full Saturday must not spend Tuesday’s money, the limit is daily at the weekend and the rest waits. Weekly is left on and the system spends ahead on Friday. Monday, which needed filling, wakes up with no budget. The weekly cap in writing and, if needed, a daily cap on the day that is already full. Both numbers go in the same message, with the review date.
