I thought you did a great job with both docs yesterday at office hours. The ___ was at the right abstraction level and is super clear. It's a multi-dimensional, complex problem and you did a tremendous job spelling it out.
I wanted to give you feedback to help you deliver such excellent content even better. I recommend working on improving your public speaking: 1) you should be able to speak with a lot more confidence 2) you really, really need to cut filler words such as "like" out. The last one is really dumb, but important. Every time you add "like", you dilute an otherwise on-point message.
I had the same problem. What helped was to write the word "like" on a piece of paper and stick it on my monitor to remind myself not to say it.
Hope this helps!
