We present preliminary results from Rosenbluth separations for elastic p(e,p) scattering performed at Q2=2.64, 3.20, and 4.10 GeV2. Several improvements were made in the technique leading considerably higher precision than achieved in previous measurements. The electric (GE) and magnetic (GM) form factors were found to approximately "scale", i.e. μp GE/GM 1, consistent with previous Rosenbluth separation results but inconsistent with polarization transfer measurements which report μp GE/GM falling linearly with Q2.
