No anchor links on that page, so I'll just quote some snippets here:
Level 1 inputs are quoted prices in active markets for identical assets or liabilities that the entity can access at the measurement date.
Level 2 inputs are inputs other than quoted market prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3 inputs inputs are unobservable inputs for the asset or liability. [IFRS 13:86]
Unobservable inputs are used to measure fair value to the extent that relevant observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. An entity develops unobservable inputs using the best information available in the circumstances, which might include the entity's own data, taking into account all information about market participant assumptions that is reasonably available.
We would need an accountant for a proper answer to that question. My perception is that they look at changes more carefully than at continuing practices and that material changes above a certain threshold need to be mentioned in the yearly report. So the effect clearly is inertia, which I would feel is a plus.
