    That's all for 1H at Q^2 = 0.5 GeV^2!

    We probably should not include the data before the hadron arm angle change, so the
    total is more like 100M T5 counts.

    Q2=.5 Helium

    The REALS constitute 1/2 of total T5 (i.e. half random/half real).
    So we need to get double original estimate of T5 to obtain required # reals.
    254M gives about 2.5% stat. uncertainty in Ge/Gm.

    As of run 1268, the coincidence timing gate was reduced to 50 ns
    The new real/total ratio is (for 16 uA): 0.58

    1268 1.1 46.9

    The beam current for run 1269 increased to 22 uA
    The new real/total ratio is (for 22 uA): 0.52 - roughly where we started.
