Dear Moritz, Matt and Dennis,

This is a very interesting combination of a wealth of physics results!
We realize this is a CONF note and not a paper, but given the interest 
this result might attract, a few things could need a word of explanation 
perhaps?

Cheers, Niels on behalf of Nikhef/VU


General/Questions
------------------
1) We would like to keep the mentioning of the "robust result" consistent
throughout. Now, "B(s)->D(s)K(*)" and "B->DK-like" are used.
We would prefer the latter.

2) L.77/78 Q: Is there anything different from using the 3 fb-1 result as 
compared to using the 1+2 fb-1 results separately? Perhaps an extra sentence
on the changes is interesting?

3) L.84 Q: It is not clear from the sentence whether the previous combination 
did _not_ include GLS, or only 1 fb-1 ?
L.104 Same question for the GLW/ADS with K*0.
L.110 Same question for TD DsK.
Perhaps it is enough to put "using 3 fb-1" between brackets: "(using 3 fb-1)".

4) L.91-93 Q: "For the robust combination ... to cancel any information 
from the B->Dpi system." Could you maybe add in one sentence how the 
B->Dpi decays enter in the robust combination?

5) Ordering of Tables / Figures on pages 11-13:
* Would Tab.3 and Tab.5 fit on the same page, to make the comparison easier?
* Tab. 4 could fit on same page as Tab.2 ?
* Would Fig.2 and Fig.3 fit on the same page?



Abstract
--------
L.2 "from time integrated" -> "from the time integrated" 
L.5 "K+pi-pi+pi-" has moved to the end of the line somehow.

1 Intro
--------
L.35 "a low value of the ratio r_Dpi that is 
not away from zero at large enough significance, is" ->
"a small value of the ratio r_Dpi that is not 
significantly different from zero, is"

Tab.1 caption: "Ref. [1], they are" -> "Ref. [1]. They are"

Tab.1 [Move to bottom of the page]

2 LHCb input
------------
L.63 "The full set of _measured_ observables is"

L.65, L.72 [Sentence is unclear. How about:]
" .... in the Appendix. The systematic correlations were not used before."

L.70 "Equations 1-3" -> "Eqs. (1-3)"

L.87 + 107 + 123
"statistical, the second is systematic." ->
"statistical and the second is systematic."

Eq.(34) "(syst),. " ->  "(syst). "

L.106 "for the observables" -> "for the measured observables"

3 Aux input
------------
L.134 "is very non-Gaussian" -> "is non-Gaussian"
"It is used in a " -> "It is therefore used in a "

L.144 "The ratio is calculated to be"

4 Results
---------
Tab.2 [How about adding a title-row, like "Analysis" or "Decay", and 
"Obervables". Also for the lower half you could insert a title-row with
"Experiments" and "Auxiliary input" or so.]
 
L.186 "gamma=72.8 " -> "gamma=72.9"

L.189 "At the 95% confidence level, both combinations agree very well." ->
"The 95% confidence level intervals agree between both combinations." 

5 Validation
------------
L.195 ", and a toy-based approach." ->
", and secondly, using a toy-based approach."

L.200 "point to overly conservative systematic" ->
"point to an overestimate of systematic"
