The tests you are conducting are quite interesting, as they could serve as good use cases for those wondering which strategies are feasible to implement for growing their HP.

I've also observed that delegating to curation projects provides lesser rewards, which I believe is because they're not focused on maximizing their curation returns.

I still think that controlling your own HP for curation is more beneficial, provided you have the time and energy to actively curate efficiently. It has been established on this platform that votes with higher value have significant social impact as well.

However, I feel that it takes more than just high HP; it also depends on your overall interaction with other users on the platform.

All the best! I look forward to your updates soon. You're doing great on your journey – keep it up!
