Dear Larry et al.,

This is very challenging experiment and I am glad that experimental results are now going to be published.
However I have a comment regarding the claim on the significance of this data to resolve a proton form factor puzzle.
Comments by Charles, Reinhard and Sebastian on the change of title coincide with  own assessment. 

In addition I would suggest that in conclusions on  page 5 the statement :
"The results are much more precise than previous measurements (period is missing)"  to be changed 
to something more moderate like: "The results of this experiment show clear trend for unpolarized measurement to be 
consistent with polarized measurement when TPE contribution is taken into account."

It is a nice piece of work and deserves to be submitted to PRL, but has to be toned down.

Best regards,
Moskov.
