Reserve growth and collection growth must work together. If a target uses the entire balance, a slow payback can prevent participation in later auctions. If a cheaper target produces a visible increase while keeping cash available, it may fit the current account better even if it looks less exciting.
This process also handles uncertainty honestly. An Observed input comes from a clean before-and-after check. An Estimated input may contain other changes. Unknown means you should make the bid decision from affordability and reserve alone. Keeping those states separate prevents a rough guess from becoming a precise-looking promise.
