Recently it came to my knowledge that it’s preferably to upload almost every change you do, instead of doing several changes and then uploading them, because this raises your amount of changesets, which is what other are looking into others. They don’t look how many changes you do in OpenStreetMap, but rather how many changesets you have.
What I was doing till 2 days ago was pretty much 1 changeset = ~80-100 changes, mostly because the iD was going red after 100 changes. So, even though I’ve done a lot of changes, for example in my area, to another person it may not look enough to be considered.
Now I do 1 changeset = ~10 changes.
The reason I was doing that previously is because of my way of thinking for Wikimedia-related edits. Few and massive edits rather than several and changes of like a sentence at a time.
