Ok, didn't go for the full 65,536 pages.

Set initially to transfer 16 pages which brought it down to something considerably less.

Then upped it to transfer 64 pages which only improved it by about 20 minutes.

** Final result: a few minutes over 5 hrs

This is probably slightly higher than your original estimate (@Tumbleweed) due to having to transfer each page (very brief but does add up I guess).

Thank you!!!
