I am so addicted to SteemWorld, I'm on it nearly as much as I'm on steempeak!

You will be maybe the only person who can answer these questions for me, see images:

See like 11% of curation reward taken for 'payout burn' but compare to this older post:

This only has nearly 2% taken for 'payout burn'..

Please explain what is payout burn and why can the percents be so wildly different? Ok math was never my strong suit I see the percents are off because one post is being paid out a lot more than the other but I still don't understand what this burn is.

And on the second image I included a cell called 'Transfer Amount" with a steem value there.. this is listed with all posts too..what is that about?

I'm new to steem so if these sound like dumb questions, they are rather curious questions for me!
