It's still accurate as far as I know.
However I'll gratefully accept any reports of errors or omissions,
admin@bitcoinfees.com or PM me
I think there should be an addition that sending a payment that qualifies as free, although it will go through eventually, can take a long time. I've had one take up to 36 hours to get into a block when sending 1.3 BTC.
Thanks. Although the text doesn't say that, something like that is written in the last image.
"sometimes more than 24hrs"
I'll have it added to the actual text somewhere.
