Popis:	We present preliminary results of a test of our dynamical overlap simulations, where we calculate the unrenormalized chiral condensate from a direct calculation, the overlap eigenvalue distribution and the topological susceptibility. We observe a (as yet) unrenormalized chiral condensate of − ( 249 ( 18 ) MeV ) 3 , with good agreement between the various methods.
