text: Backwards-checking formula for the debt reduction bechmark (bbt):bbt = 60% + 0.95*(bt-1-60%)/3 + 0.952*(bt-2-60%)/3 + 0.953*(bt-3-60%)/3. The bb-value is the calculated benchmark limit for year t. The formula feature three t-year-indexes for backwards-checking.
  Forwards-checking formula for the debt reduction bechmark (bbt+2):bbt+2 = 60% + 0.95*(bt+1-60%)/3 + 0.952*(bt-60%)/3 + 0.953*(bt-1-60%)/3. When checking forwards, the same formula is applied as the backwards-checking formula, just with all the t-year-indexes being pushed two years forward.
  The year referred to as t in the backward-looking and forward-looking formula listed above, is always the latest completed fiscal year with available outturn data. For example, a backward-check conducted in 2024 will always check whether outturn data from the completed 2023 fiscal year (t) featured a debt-to-GDP ratio (bt) at a level respecting the "2023 debt reduction benchmark" (bbt) calculated on basis of outturn data for the debt-to-GDP ratio from 2020+2021+2022, while the forward-looking check conducted in 2024 will be all about whether the forecast 2025-data (bt+2) will respect the "2025 debt reduction benchmark" (bbt+2) calculated on basis of debt-to-GDP ratio data for 2022+2023+2024. It shall be noted, that whenever a b input-value (debt-to-GDP ratio) is recorded/forecast below 60%, its data-input shall be replaced by a fictive 60% value in the formula.
