Steam Download ports for QoS Packet Scheduling

Hi everyone, I'm looking for an updated list of the ports steam uses for downloads. I found the official list Here, but its definitely wrong or incomplete. My router lists the local listening ports, and while the connection table occasionally lists the 27000 range on the server end, none of the ports listed on the official list are used locally. I want to ensure that Steam doesn't saturate the connection entirely, and put steam downloads on a lower QoS tier, but I cannot do so if its going to randomly choose ports in ranges I haven't listed.

Here is my assigned ports for the local IP in question, this is mid-download of Elite: Dangerous (if that makes a difference)

Code:

---

Destination    Proto. Port range  Redirect to    Local port
ALL            TCP    53802      192.168.2.5    53802     
ALL            UDP    53802      192.168.2.5    53802     
ALL            TCP    64411      192.168.2.5    64411     
ALL            TCP    4433        192.168.2.5    4433     
ALL            UDP    64411      192.168.2.5    64411     
ALL            UDP    40584      192.168.2.5    40584     
ALL            TCP    40584      192.168.2.5    40584

Any help would be much appreciated.
