Interesting analysis. I am currently ranked at 2150 in terms of HP. I spent a few months practically inactive in posting on the hive due to high workload and exhaustion. However, I remained active on Splinterlands, where we currently have the largest active Brazilian guild.

I think that some factors are very interesting in these assessments of differences. Well, in my opinion, some factors are:

I totally agree when you mention the time on the account because if you analyze a person who has been on the hive for a long time, in addition to the issue of rewards, it also shows that they are a person who has not given up on the project and is still with it.

I also agree that engagement makes a difference. People who comment, like, and seek to create a family, identifying themselves and living in the hive projects, end up achieving greater appreciation. Consequently, greater engagement in the projects can lead to more favorable curation.

I believe that consistent posting has a lot of influence because you strengthen the bond where people continue to follow you and discuss, helping with engagement and rewards.

Some additional factors that I feel are:
When a person is part of a community that teaches and guides the user to seek the best practices in the hive, it helps a lot, because the hive is not that simple, it is a living ecosystem where many things often change.

Compliments, when a person is complimented, they feel motivated to continue posting, so the more positivity you have in your circle of people in the hive, the better you evolve. As the saying goes, if you are with 5 people who are trying to move up, you will be the sixth to evolve.

I believe that the higher your HP and activity, the more likely you are to seek to be part of the "hive" team. You stop thinking about posting "just to earn a few bucks" and focus on evolving by bringing more people closer.

I myself always try to help people who play Splinterlands to evolve and increase the players in my country, it's something that I think is very good about the brawls and the dialogue, in the summary of this text, I believe that the more you think about the community, the more you will evolve and multiply your earnings and friends.
