[Clas12_rgb] do we really need the empty target run?

Dear all,
in the spring run we took 174M events with empty target, and in the fall
we took 51M more. Do we really need to take more empty target data
tonight?
The only difference between the spring data and now is the beam energy,
while in the fall we had same energy as now but opposite torus polarity.
I am just asking this because we finally have a very very nice beam, and
it seems a bit sad to waste 5 hours of it for data that maybe no one will
ever analyze. Or will anyone? It wasn't clear at yesterda's RC meeting...
Thanks for your feedback - and don't forget tomorrow's party at noon at
the ResFac!
Silvia
