If I may offer the following comments:

Slide 26: When you say =93Excellent agreement with VEPP-3 generator," I jus=
t want to caution that our order alpha^3 has excellent agreement with the V=
EPP-3 generator. But our =93all orders=94 mode isn=92t something that the V=
EPP-3 generator can do. And as you can see on slide 27, =93all orders=94 is=
 about 1% different from order alpha^3. The only way we=92ve validated our =
=93all orders=94 calculation has been the convergence to Maximon + Tjon as =
Delta E -> 0.

Slides 28-32: This is an effective way to show how one could separate backg=
round from elastic events. However, I caution that it is not how the final =
analysis was done. This method was my first approach, but we (Jan, Brian, m=
e, Becky et al.) discovered that it has deficits, and so we changed our app=
roach to something more sophisticated. =


Slide 35: I=92m not exactly sure what you intend to communicate with this s=
lide. If it is helpful, I offer figure 8-12 in my thesis as un-blinded vers=
ion.

Slide 42: You say that VEPP-3 has 3 different beam energies. I=92ve only se=
en data from 2. What=92s your source?


Hope these are helpful. Good luck,
Axel
