In some circumstances you may be able to refine the estimate as the
message is being transmitted.
Chunk extensions ("chunk-extension") would suit that:
1000;estimated-remaining=299000
(1000 bytes)
1000;estimated-remaining=298000
(1000 bytes)
I don't know if chunk extensions break in the real world, though.
