There is lots of talk about no limit to venting. Take some time and read the Update to the article, "Balancing Steam Systems" by Gerry Gill and Steve Pajek. This article is amazingly helpful for two reasons, first it provide a table of venting capabilities of many, many vent valves, and you can see how they relate to each other for your situations. Second, there is an eye opening update, "Can you vent too fast?" I had Varivalves installed throughout my system with many fully open. I also added up to two Gorton #4s at different locations in the condensate return. I couldn't come close to balancing the system until I removed the #4s and swapped out the Varivalves (fully open is like a #1, shut is like a #5) for Maid O' Mists with individual orifices. I even had to get some Vent Rite #1s so I could further reduce the vent rate in overheating apartments, below a #4.
Bottom line, I am now a true believer that a system can be overvented.
Take the time and at least read the update, https://heatinghelp.com/systems-help-center/balancing-steam-systems-using-a-vent-capacity-chart
