Ah yeah. It occured to me afterwards that composting for an apartment or balcony would be a lot different.
I'm not too sure what would be a full batch. It's only been a few years and each year is a little different. What I have noticed is that whatever is growing around those dumping spots tend to grow way more compared to other areas.
For example one dumping spot was surrounded by tomato and cucumber plants. I struggled to keep those plants trimmed and at a reasonable size. I'm assuming the roots of those plants grew in the direction of all that constant, fresh compost.
I'll probably give the top layer of soil a good mixing next spring to spread out the compost. I'm trying to work towards a no till or minimal tilling for my gardens so I'm still experimenting and observing. I'm also trying to find a way to do this all with as few tools or products as possible while keeping it as local as possible.
