Hi, the sync short blocks doesn't know how long the frame is. It just recognized that there is one. Since it doesn't know the length, it forwards samples corresponding to a "large" frame into the flow graph. If the frame is shorter, needless samples are dropped at a later stage.
IIRC, the actual maximum frame size allowed by the standard is above 2000 byte. I set max samples so that a 1500 byte BPSK1/2 frame can still be decoded, i.e., such a frame should have around 540 OFDM symbols with 80 samples each.
