A summary of the main points of discussion raised during the talks and their follow-up questions, as well as in the round table of the last day of the αs(2019) workshop, is presented. The discussions not only focused on particular issues affecting each one of the individual αs extractions, but also on the current PDG categorization of αs measurements and on the methods used to average them into a single αs(mZ) value. Most of the listed points are open and sources of potential controversies, which we highlight here as one might expect that ongoing progress in the field will lead to their clarification and resolution.

Abstract
A summary of the main points of discussion raised during the talks and their follow-up questions, as well as in the round table of the last day of the αs(2019) workshop, is presented. The discussions not only focused on particular issues affecting each one of the individual αs extractions, but also on the current PDG categorization of αs measurements and on the methods used to average them into a single αs(mZ) value. Most of the listed points are open and sources of potential controversies, which we highlight here as one might expect that ongoing progress in the field will lead to their clarification and resolution.
