The original version of this article, published on 22 August 2020, unfortunately contained a mistake. The following correction has therefore been made in the original: The second equation in paragraph “VED calculation” was incorrect; the corrected equation is given below. The original article has been corrected.

$$ \left(\mathrm{V}1\times \Delta \mathrm{Art}\%1+\mathrm{V}2\times \Delta \mathrm{Art}\%2\right)/\left(\mathrm{V}1+\mathrm{V}2\right)\times 100 $$
