Thank you Carlos, for putting this together and for representing us. 
Here are my comments. I hope they are helpful.

Break a leg tomorrow,
Axel

- Slide 3 is a lot wordier than I think it needs to be. If it were me, I would make the title "LAD will test the EMC-SRC hypothesis" and then put critical information in bullets, e.g.,:
	- Spectator-tagged DIS on deuterium
	- new Large Acceptance Detector
		- tag protons in 200–700 MeV/c range
	- Learn about the partonic structure of nucleons in SRCs

I offer that as one non-unique suggestion for how you could reduce the amount of text without sacrificing critical information.

- Slide 4: Just FYI, the genesis of those images was a talk I made for the Bled workshop in 2017. I don't care about credit. I do worry about and regret my choice to use the word "jet." How jet-like are these hadronic remnants? I don't know. That was the kind of word choice one makes when one is young, inexperienced, and believes that "1 parton struck ===> 1 jet emitted" was a universal truth. 

- Slide 5: Ah, I see you have updated the graphics to be more realistic. Nice. I may steal that for the future. 

- Slide 6: Just FYI, these were not produced with SIMC. This simulation came from my toy MC. The dashed lines contain the coverage provided by HMS+LAD, and SHMS+LAD respectively. (theta_pq is not an inclusive variable). I hope that is clear.

- Slide 17 has the models from the Melnitchouk / Sargsian / Strikman paper. In order from top to bottom, they are the "Binding", "Rescaling" and "Suppression of Point-Like Configurations (PLCs)" models. The are specifically for x'=0.6 / x'=0.3. Meanwhile our projected uncertainties are for some x' ranges, probably x'>0.45 /   (0.25 < x < 0.35). These details aren't critical to write down, but you should be aware. If questions come up, you can refer back to me, the group, for more info on how this simulation was run.

- Slide 18, Dien's last name is spelled Nguyen.
