I was wondering when it makes sense for someone to set voting power to a small percentage (say, 5%).

One situation would be when someone has a large amount of Hive Power (or Leo Power here) and needs to scale down voting power to make sure the upvote is still a good amount. The veterans here know what I'm talking about.

Another situation would be if voting power is close to being depleted. That would be more common for someone in my situation where my HP/LP is in 3 digits.

I'm asking because I've been seeing a large number of upvotes set at 5% yet the HP over the voters is barely at dust threshold or beneath it. Most of these upvotes come from new Hivers, but some come from Steemian-era Hivers who haven't been active on the blog side in a long time.

Once day I want to adjust my voting percentage to a small number because my HP is large; I'm not there yet, so I still keep at at 100%.

There could be some curation trails I picked up in recent weeks, in which case people may not even know about their voting power percentages.

What other situations make it understandable to set voting power to 5%?
