Query: Small $P_{\perp}^2$ Elastic Proton-Proton Polarization near 300 GeV   Using two hopefully reasonable assumptions plus existing data on the
analyzing power in high energy proton-proton elastic scattering, we estimate
that the hadronic helicity-flip amplitude at $P^2_{\perp}$ of 0.003 (GeV/c)$^2$
is neglible near 300 GeV. This would allow the absolute calibration of a CNI
polarimeter.
