Scavenger Stations

I've been assigning unassigned settlers to scavenger stations so that they're pulling their share of the load but I was wondering how much this really help. I found some good info on the Fallout Wikia.

Normally, unassigned settlers will scavenge by themselves at a rate of one random junk item per day (in game day I assume) when assigned to a scavenger station they can collect two random junk items per day.

This was basically what I thought it was but the following was of most interest:

Once the total number of junk items in the workshop reaches 100 + (population × 5), no more junk items will be added to the workshop in either case.

So there is a limit on how much can be scavenged at which point they will stop. So how to resolve this? Do we have to clean out all the junk from a workbench when it reaches or looks like it's reaching, capacity? Would it help to manually scrap the junk in a workbench? Players have mentioned that they move junk from a scrapping settlement to another settlement where they aren't doing scrapping. This really sounds like a pain in the butt.

I'm not sure what the best solution is but I'll keep looking.

Another interesting thing is that scavenger stations can be wrecked in an attack. There is no external indicator. You have to cursor over it in build mode and it will give you the option to repair it.
