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 of 0.003 (GeV/c)2 is neglible near 300 GeV. This would allow the absolute calibration of a CNI polarimeter.
