On the serious side:
I have never heard any good explanation of this behaviour. The copy function knows how many files it must open for read, how many for write - presumably the same number, but the time required for preparing write operations could be different from read. In any case, the time is roughly the same for every file on a given disk. To open the file, the MFD entry ("inode", for you *nix guys) is inspected. It also tells about the size of each file, so you roughly know how many pages will be read from or written to the disk - at least you know the difference between kB, MB and GB size files. You have a rough idea about the transfer speed, based on the disk technology. If you don't, after opening a couple of files, that will tell you the time overhead per file. After you have copied a few megabytes, you roughly know the transfer speed.
I am certainly not expecting a three decimals correct figure. I just cannot fathom how it can jump up and down by magnitudes, even after the copy operation has been running for a while, with empirical figures right at your fingertips.
I am not sure why exactly, the letters for an anagram are mostly there. Maybe taking the end of "laps" (s) and dropping the "y" from "lady" (because of "first") and you get "lads in car" which would be the anagram... I dunno...

It's obvious she was in a car and he is a churchy bloke with 9 letters.

And I got to thinking: if a geek was stranded on a desert island, what website would you take with you ("reader only"- you can't contribute or post at all, or it'd always be "search and rescue" or similar)?
WikiHow could be handy?
How about you?
