This was a very nice presentation.  You stayed within time and did not have to rush.  I do have a few suggestions for you, but not many.

Slide 3: I think you can spend a bit more time talking about the figure shown here (don't call it a plot!).  

Slide 4: Between slides 3 and 4, you need to define the sTGC acronym.  Folks outside ATLAS will not know what this is.

Slide 7: Try to avoid parentheses within parentheses.  I think the outer ones aren't needed.  Spelling check on signal.

Slide 8: You should define what pi-network is if you want people to follow your argument.

Slide 11: There's a lot going on in these figures and you don't discuss them much.  If you don't need to discuss all of the figure details, it's better to not show all of them.  This would give you time to talk about what's happening in each figure.

Slides 12/13: I think you're using scintillator triggers for this.  If so, you should just state it.  If not, then I missed something.

 

Best regards,
