Dear Marathon Spokespersons,

Thank you very much for your work getting together the new manuscript together; but I have some concerns about how you are presenting Jefferson Lab experimental results.

Going back to the raw data (i.e. what we measured) there is no significant difference between the Hall A or C, yet Fig. 3 of the manuscript makes it look like Hall A & C are in disagreement.

( Figures from Kent State library:  http://rave.ohiolink.edu/etdc/view?acc_num=kent1587232156043952 )

Even with the iso-scaler correction there is no significant difference between data sets.

It is fine to do a Bayesian type analysis as done in this work, but the Frequentist result must be clearly shown first and we should be clear that the raw results all are in reasonable agreement.

The famous example for why this is important comes from neutrino mass measurements, where “everyone knew” the mass was positive:

Best Wishes,
Douglas
