Yeah I'm glad I tested it before I fought a real Raiden, I wonder if this is akin too his rise speed. It doesn't happen to Benimaru or Yuri's air throw they still get the knock down sound cue, but he rises too fast so a safe jump won't work so that maybe just his rise speed, but the Mai Shiranui air throw situation is different I mean no knockdown sound, it's more like he landed on pillows.
