How fast does the Discord orb travel?

Information online doesn't seem to exist regarding the flight speed of both his Orbs of Destruction (weapon) and the Orb of Discord that is his debuff.

To test this out I started a custom game vs me and a few easy-level Bastion bots. The testing stage was Hanamura, with me on defenders, waiting close to the gate, with the Bastions coming out of spawn as normal.

I tested this by charging up the orbs a few seconds before the match was set to start, then waiting for the Bastions to walk in a straight line towards my position. I let go of the orbs then attempted to fire a Discord; from testing it multiple times the Discord orb always debuffed them after the orbs of destruction had hit the Bastion already.

If further research shows more technical info I will update this answer accordingly, but anecdotally from testing it the Discord orb is much slower than his regular orbs of destruction (although it does home in on enemies)
