[Clascomment] OPT-IN: New scaling measurements map the transition from single-particle to correlated-pair dominance in atomic nuclei

[Sebastian Kuhn]

One minor suggestion: 
line 70-71 "can account for up to 20% of the nucleons in the nucleus" better "can account for up to 20% of the nuclear response"

Fig. 1 Caption: The first "sentence" after the headline is not a sentence (but all others are). Add a verb! Also, the caption is confusing - you introduce sigma_CM, E*, and the "intrinsic width of the missing mass" without explaining how those hang together (or what one should learn from Fig. 1).  You should also provide a reference for the GCF calculation IN the caption (captions should be self-sufficient or refer to a specific part of the text). "Contract" is misspelled.

Meanwhile the text (line 116) introduces YET another quantity, Emiss. (You should mention that this is only the "missing energy" if the nucleon is initially at rest!).

In general, I'm afraid the message you are trying to convey (to a Nature audience, not to experts) may get buried in too many variables, side explorations, and hidden assumptions that you of course are aware of but the general readership may not. (I got lost reading the paper, and I do have some experience with this topic!) Is there any way to simplify the message, keep only the absolute necessary variables, reduce the amount of information relegated to the "extended data" section (which really is crucial to understanding the paper itself), and follow a clear, logical narrative where the Figures go with the text and show quantities introduced there?
