How to interpret the result

Common mistakes and limitations
- Inconsistent scope
- Changing the included business units, products, channels, or populations makes the trend look different even when underlying performance is unchanged.
- Mismatched periods
- Formula inputs from different cut-off dates or time windows do not describe one coherent result.
- Mixing accounting treatments
- Gross and net amounts, recognition dates, allocations, refunds, taxes, and capitalisation rules must be applied consistently.
- Assuming one universal target
- A useful comparison depends on accounting policy, revenue model, company size, capital structure, seasonality, and reporting period; use like-for-like internal trends and clearly documented peer groups.
