Here are a bunch of examples of hitting EOT, sorted by amount written.
(Note that one is very short; this was because FOO_900 was a DDS1 tape.)

I can see two "peaks" here. One around 3600 MB and one around 3900 MB.
I have a strong belief that some of your tapes are using both hardware
compression and software compression. 3600 MB is the expected capacity
when doing this.
When I do the same with some older data, I get just one small peak,
around 3940 Mbyte.
The first few lines are real tape errors (I upgraded to AIT-1 tapes,
when my DDS2 drive became unreliable).
