the simulator only allows simulation on a subframe basis. This is due to LTE’s structure is based on this time interval which the simulator tries to simulate accurately.
I am sorry for the confusion regarding the documentation. What we wanted to express with this “50 (2000)”, is that we set the quicktest scripts to 50 subframes when shipping to make the first simulation run quicker. For the figures we included in the documentation we used 2000 subframes in order to get more significant results to compare to.
