Thank you @remlaps. The idea of measuring payout per active feed placement is very interesting. It would approach the reward system from a completely different angle — looking not only at who receives rewards, but also at the potential audience and attention generated by those rewards. This could definitely be worth investigating in a future analysis.

Regarding @thoth.test, now that you mention it, I remember the project and how it works. I had simply forgotten about it when doing this analysis. That also explains very well why the account showed such a high number of self-comments and self-votes while the actual author rewards were extremely small.

Thanks for the reminder and for adding another interesting perspective to the discussion.
