This is only in -depth explanation that is clear and well structured and paced. Thanks a lot!

[@ChristophStoettner]

Thanks, Philipp, this explained a lot of things in detail. One tiny thing: Please repeat questions from the audience, so remote attendees get the point too. Or NDC, can you add microphones for questions next time please?

[@markocurlin541]

I second this. Even if it isn't word for word, a general idea of the question means a lot.
