 The basic ida is to first do a study on the purely pQCD level. Different shower algorithms should be compared at LO+PS level first, along with their recommended variations. The basic ida is to first do a study on the purely pQCD level.

-A comparison to analytic resummation (where possible) and at different levels of perturbative accuracy is desireable. The range of observables should be kept small and concise, ranging from quantities which exhibit resummation,​ transition and fixed order regions, but also including these observables,​ where shower uncertainties are expected to indicate large hadronization corrections,​ as well.+A comparison to analytic resummation (where possible) and at different levels of perturbative accuracy is desirable.
