This is one of the best and detailed reviews. I appreciate it, however, there are certain areas that need to be put in order.

I once again appreciate your detailed review.

If you proactively use the Steemit platform with the activeness of creating a post, commenting on other posts, Up-vote to other posts, and when you do all these activities by considering the above % value of VP and RC then your Steem Power will get keep increase which effect on your Reputation which will also get an increase.

No, reputation has more to do with the upvoter's SP size. It is true that if you remain more active you are more likely to gain the attention of curators and hence upvotes which ultimately result in gaining a good reputation. But to gain more reputation score is to attract more upvotes and what is the SP and voting weight behind those upvotes, that will determine your reputation.

you can give your Steep Power to someone for a particular duration, in other words, you are allowing someone to use your Steem Power and in return, you will get some rewards as an interest basis on daily, weekly, monthly. You can extend the delegation period or you can cancel the delegation any time as you want.

Blockchain does not reward you for delegating your SP to someone. However, you may remain in an agreement with the delegate to earn daily, weekly, monthly delegation reward which is mutually agreed upon between the delegator and delegate.

Curation Rewards:- When you make comments or votes to posts created by others, so in return, you get rewards for that comments and votes which you have given, this rewards call as a Curation Rewards.

Curation reward is simply 50% of your upvote value which you most likely to get in general circumstances. So when you give an upvote to other's post/comment, you will earn a curation reward.

Thank you so much.
