The rankings of keywords in the Performance Tracking modules are calculated in the most neutral way possible to simulate the best results possible.
Several characteristics are taken into account:
Amount of search history
A cookie is generated on each call
Always in offline mode
A large pool of IP addresses in many countries
We always ask Google. TLD, and not a precise datacenter via IP address (in order to mimic human behavior)
For this reason, it is possible that the displayed position differs from that displayed in your searches.
