Reading Frame Data

Hello guys. I am starting to try and learn SFV a bit more seriously and am a bit confused with frame data. I don’t know if I am not reading it correctly or if there is something else going on that I don’t know about. I am playing Juri and one of her basic combos is cr lk to standing lp to heavy dp. I am trying to understand why cr lk combos into st lp when from what I understand in the frame data cr lk is only +2 on hit while st lp has a 3 frame start. I’m assuming I am not reading this quite right as they obviously combo, I just can’t see that looking at the frame data. Any help would be great, thanks guys.
