-within 2 blocks before it confirms 0.0010154 btc/kb
-within 5 blocks 0.00083274 btc/kb
-within 10 blocks 0.00069784 btc/kb
-within 25 blocks. 0.00069784 btc/kb
so here is your maths works out as U.S dollar
next block pay over $1/kb (40cent tx average)
within 2 block pay over $0.76/kb (30cent tx average)
within 5 block pay over $0.63/kb (25cent tx average)
within 10 block pay over $0.53/kb (21cent tx average)
within 25 block pay over $0.53/kb (21cent tx average)
silly high prices electrum is "average estimating" and guess what...even then its not a guarantee.
the only issue is if 5000 people all paid 0.0015231 btc/kb
only ~2500 will get into the next block because there is a limit.
laving the other half waiting
no one knows who/which one of them people paying over $1 a kb will get it.
theres usually a 3 groups of people that will always pay the top fee, no matter what
1. i need it now theres someone im trading with looking at his watch, tutting and moaning
2. i just dont want the hassle of keep checking the blockchain or having to rebroadcast and/or calculate fee's
3. if i pay more i naively dont understand bitcoin and think it will confirm in 20 seconds by paying more.
now then. there is no way to guarantee any of the 3 groups get in first..
now then, there is no way to guarantee group 1 gets higher priority to go first(real need).
even when paying obsurd amounts of 40cents per average tx ($1/kb)
summary
fee estimates alone do no work. especially in a spoonfed sheep herd crowd
there needs to be a PROPER WORKING secondary mechanism BASED ON CODE and flags to highlight real priority of the herd crowd of "just pay more" spoonfed people
