Since 800*10=8000MB and the test box had only 4GB, I assume your
numbers (0-10, 10-800, 800+) are expressed in MB and not in
blocks, correct?

Sure. I also think this should not refrain yourself to go on with the

thread to try to get us organized, unless someone else is faster than
me (hint, hint).

I'll try to run the same tests today.
