Wrong estimated time when copying 270GB between drives

Anyone else noticed this?

I copied about 270GB of files from one drive (almost full) to a new 500GB
drive.

Estimate started at 8 days - which I wasn't surprised at - as usually it
starts conservatively and then drops as some data gets transferred.

Though as it progressed it grew up to 32 days or so.... even while it was
moving at 55MB/sec... and had transferred 50GB or so.

Then after 1/2 the data was transferred (after 15 mins? or so) it dropped
down to 3 hours. Progress bar was showing about 10% then.

Something in the estimation is screwed up I think.

It is an estimate and never even close. Too many things affect the transfer
speeds. Either things you are doing while it is copying or things Windows is
doing behind the scenes. I don't know why Microsoft even bothered. On the
plus side it seems work like it does in XP.
