First, the level of competition is evaluated for each contract, and these levels are then averaged across all contracts for a given contracting authority, to give a partial indicator "//​k//"​. ​ This indicator is calculated in a two-step process. First, the level of competition is evaluated for each contract, and these levels are then averaged across all contracts for a given contracting authority, to give a partial indicator "//​k//"​. ​ - Our calculation of k also reflects the fact that different markets are subject to different levels of competition. We compare the results for all contracts against the [[http://​en.wikipedia.org/​wiki/​Median|median]] number of tenders in contracts with the same or closely related [[en:​cpv_ciselniky|CPV code]]. To maximise precision but avoid misleading statistics, this median value is calculated for the most detailed relevant level of CPV that has at least 20 contracts awarded. The sub-indicator "//​k//"​ thus compares the number of tenders submitted for a particular call with the usual number of tenders for that contract subject. If the median value cannot be obtained for specific tender (typically in small scale tenders), it is set equal to 1 and thus every level of competition is positively evaluated. + Our calculation of k also reflects the fact that different markets are subject to different levels of competition.
