Rocket League: Heatseeker (4-Minute Pink Ball Rally/Speed Unknown)

Sorry, I don't know the ball speed. I had no idea that was a thing some people needed to know while watching Rocket League videos. We were just chilling and having a casual game when this rally unexpectedly happened. This is a video of the replay, it wasn't captured live.
TBH, none of us really cared much about the ball speed when the goal was finally scored. As fast as the pink ball goes in a Heatseeker rally, it does stop building speed after half-a-dozen or so hits anyway, so there's no discernible difference between the 10th hit and the 100th hit. And none of us thought it was a speed of any significance -- I don't think it was even going much faster than a typical pinch shot.
Again, sorry if you wanted to know these things. I'm posting this because it was a fun rally, not to show off the ball speed.
