We've wondered about that ourselves.
The ranges available on the online tool are fairly linear. They go from ‑25% to 25%. Beyond that, the linearity begins to break down. That's the main reason why we limited ourselves to plus or minus 25%. Indeed, the linearity, based on historical data over the past six years, is pretty much in that range. However, if we go beyond it, whether upwards or downwards, there's a risk of losing linearity. There could be a complete collapse or exponential growth in certain indirect capabilities, particularly for overhead.
