L 37: described in [1] and its performance in [2]... -> add Ref. [1], Ref. [2]
L 39: Run 2 is only implicitly defined

L96: "...grouped in trains of 48 bunches each, with 2544 of these colliding at the CMS interaction point". This formulation reads as if 2544 trains collide, presumably bunches is meant?
L106: If we're giving 3 significant figures here, should write 41.0 instead of 41?
L112-113: same comment

Fig 3: "The prescale columns for luminosities of 1.5 × 1034 cm−2 s−1 and 1.7 × 1034 cm−2 s−1, represented by the black and red data points, respectively, were not used to collect data at high pileup, but they were activated only when their rate was lower than 100 kHz." not clear what is meant here. It seems obvious that they were not used to collect data at high pileup,  that is why there are different columns. What information is this statement giving that isn't already in the rest of the caption? I'm almost certainly just missing something.

Table1&2: table captions should be at the top?
Table 1: what is triple + double? It's simply a triple-muon trigger with a requirement that two of the muons are from a resonance (effectively)? It's not immediately obvious from the table
Table 1: Terminology. One could simplify this; e.g. Single EG = Single e/γ assuming the particle symbols are defined somewhere else in the text (upon reading the rest of the paper I see that they do get defiend later on). Also, for "OS", the definition is given as "Opposite Sign (charge)" - could we not just write the abbreviation as "OC" and give the definition as "Opposite Charge"? 
Table 2: (jet) is written in math mode several times.

L223 "These algorithms are fully pipelined and start processing as soon as the minimum amount of data is received" -> what is "the minimum amount of data"? Is it 'as soon as any data is received at all' or is there a threshold?

L235: AMC is not explicitly defined

L238 insert 'Ref.' before [3].

L274 "in [14]" -> "in Ref. [14]"

L281 "in [15]" -> "in Ref. [15]"

L311: It is not clear from the text what a Golden Pattern is. If it is not relevant that it is a "Golden Pattern", why are we giving it a special name, instead of simply stating we use 26 patterns which encapsulate information X and differe depending on Y? If it is relevant that it is a "Golden Pattern" more explanation is needed.

L327: No need to define an acronym for local charged tracks; it is only used once in the text.

L368: "TFs have also an overlap" -> "FS also have an overlap"
L379: "course" -> "coarse"

L402-403:"The tag muon is reconstructed with the CMS particle flow algorithm with pT>26 GeV" -> rephrase. How about "The tag muon is reconstructed with the CMS particle flow algorithm, and is required to satisfy pT> 26 GeV..."

L415: another missing 'Ref.'

L420-422: Figures should be re-ordered; we're jumping from Fig 9 to Fig 13 then to Fig 12- should be Fig 9, then Fig 10, then Fig 11.

Fig 14: is there no trigger tower ring 28 or is there another reason there is no data in the plot at that point? An explanation of this feature could be helpful around here.

L 476: single-use acronym defined?

L 491: "Two working points were derived using Z➔ee collision events and an unbiased sample to estimate the rate." What is meant here: unbiased as in 'with ZeroBias trigger' or unbiased in 'with another trigger not correlated with what we're trying to measure'? (or even something else?)

L501: "using Z → ee events and a tag-and-probe technique from data recorded in 2018" not sure what is meant. "using a tag-and-probe technique applied to Z➔ee events recorded in 2018"? If so I would rephrase

L502: "common identification criteria" -> "what are these?"

L507-508: 'is required to between' -> is required to be between

L512: missing space before 'These'

L545: reference to HPS algorithm?
