Here is the spectrum of the 16949 events with gcr hits contained in the first run ([r0257895168_v002|http://glast-ground.slac.stanford.edu/DataProcessing/run.jsp?runid=257895168) of opssim2 simulation. The run lasts ~96min, so the corresponding (orbit averaged) gcr rates is 2.9 Hz, consistent with previous simulations.
