A next step to correct wrong nutritional data, starting by looking at the [https://world.openfoodfacts.org/cgi/search.pl?action=process&tagtype_0=categories&tag_contains_0=contains&tag_0=olive%20oils&sort_by=unique_scans_n&page_size=20&axis_x=fat&graph_title=Olive%20oils%20(fat%20percentage)&graph=1 fat percentage].

There are 6 products with more than 100% fat, so lets correct those first. It easier to list those with a [https://world.openfoodfacts.org/cgi/search.pl?action=process&tagtype_0=categories&tag_contains_0=contains&tag_0=olive%20oils&nutriment_0=fat&nutriment_compare_0=gt&nutriment_value_0=100&sort_by=unique_scans_n&page_size=20&axis_x=fat query] and correct them. For these products the wrong data has been added. One product had a fat content of 101g though.

Note that the distribution has two peaks, one around 100% and one around 90%. It seems that some producers assume that their olive oils consist of 100% fat and others really have it measured.

Now that I did the fat percentage, I realised that I have to go through all nutritional values and look at values that are not ordinary.
