We present a theoretical and experimental study of the subcycle interference in laser assisted XUV ionization of Ar  atoms.  Averaging  over  the  focal  volume  happens  to  blur  the  intracycle  interference,  which  thus  cannot  be  measured  directly. We show that even at these conditions, the intracycle interference can be obtained through the subtraction of two different angle and energy-resolved distributions at slightly different laser intensities.
