For an actual technical post, I would have expected vBytes to be at the very least mentioned, maybe block weight, and definitely more in depth info on transaction sizes.
wow well now this is technical. Yeah you are right and actually i was about to mention the block-weight but since i considered answering from a normal business user who want to estimate an
average fee before sending. Otherwise you answered perfectly! I did not know many things you highlighted. Thank you.
Regarding bitcoinfees.earn.com vs coinb.in i guess it's showing the lowest fee to get it into the
next few blocks where bitcoinfees.earn.com is estimating the fastest. Also i guess difference of calculating based on last 24h vs last recent block transaction giving different results.
