  We have studied the energy dependence of the $pp$ elastic scattering data and
the pion-photoproduction data at 90$^\circ$ c.m. angle in light of the new
generalized counting rule derived for exclusive processes. We show that by
including the helicity flipping amplitudes (with energy dependence given by the
generalized counting rule) and their interference with the Landshoff amplitude,
we are able to reproduce the energy dependence of all cross-section and
spin-correlation (A$_{NN}$) data available above the resonance region. The
pion-photoproduction data can also be described by this approach, but in this
case data with much finer energy spacing is needed to confirm the oscillations
about the scaling behavior.
