Thank you for preparing the recording! My main comment is that all plots need an ATLAS label. If they are not published, they need the "ATLAS Work in Progress" label as explained here: https://twiki.cern.ch/twiki/bin/view/AtlasProtected/NationalMeetingsPhysicsSchools. Few other minor comments below.
p3: You nicely said why aS is important, but it could also be pointed out in a bullet point.
p4: "to search and study new physics" is a bit vague. There is also a whole Standard Model programme dedicated to precision measurements such as yours.
p5: Minor comment about the Muon Spectrometer-- the main purpose is the identification of muons. Muon momentum is really determined from a combination of the ID and MS measurements (not MS alone).
p7: Great slide!
p8: Why was only the 2018 data used? By the 'summer data', do you mean the Run 3 data? Before adding Run 3 data it will probably be easier to add the Run 2 data from 2015, 2016, and 2017.
p10: Not clear what 'software' you are referring to. Do you mean the MC Generator software?
