By using the different cursors in the panel, the user can simulate cost variations impact (without changing the recorded data).
The initial cursors setting corresponds to the value 1 (or 100%).
When a cursor is moved to the extreme left position, this corresponds to a simulated decrease of 90% for the corresponding cost (in other words the simulated cost value corresponds to 10% of the nominal value).
When a cursor is moved to the extreme right position, this corresponds to a simulated increase of 1000% for the corresponding cost (in other words the simulated cost value corresponds to 10 times the nominal value).
The simulated value is displayed on the right of the cursor.
