The methods used for counting the indicators also partly deviate from those applied most commonly. The clearest example of this is the calculation method for Outputs in Top Citation Percentiles indicator, where the Field-weighted Citation Impact values of the publications are used for determining the limit values of the percentiles instead of their number of citations. This topic has been discussed in more detail in an article by The Bibliomagician blog (Leino & Gauffriau, 2020). The duration of the citation time window is another factor that cannot be changed when counting normalised indicators: by default, it is the year of publication and the three following years.
