You cannot produce ANY keyboard input while the tests are running.  If you
accidentally bump the keyboard, backspace over whatever you wrote and press the
enter key and it will start again.

A blank line or end of file marker or anything else which the SAN kit is crabby
about.  The thing that really bugs me is that it stops whenever it finds an
error.  Hence, if you want to process 100 rows and something is wrong with row
#2, it will stop at row 2 and not process any of the subsequent rows.  I would
rather see it:
1.  Diagnose the error exactly, putting the bad record and a DESCRIPTION of what
is wrong into the error log.
2.  Continue on its merry way with the next record.

Only 10 were unsolved.

300 EPD records in total were processed.

>total acd: 2714   mean total acd: 9.05

The average depth in plies for the whole set was just a bit over 9.

>total acn: 411804960   mean total acn: 1372683.20

The average nodes per record examined was 1.4 million.

>total acs: 2617   mean total acs: 8.72

It took just under 9 seconds per record, on average.

>total mean node frequency: 157357.65 Hz

160K NPS was the average speed.

>solve: 290   solve percent: 96.67

290/300 solved is 96.67% correct.

>solve acd: 2624   mean solve acd: 9.05

For the records that were solved, the average was a hair over 9 plies of depth.

>solve acn: 397008916   mean solve acn: 1368996.26

For the records that were solved, about 1.4 million nodes were examined

>solve acs: 2514   mean solve acs: 8.67

It took just under 9 seconds per record that was solved

>solve mean node frequency: 157919.22 Hz

The NPS speed for the records that were solved was 158K NPS

>unsol: 10   unsol percent: 3.33

Ten records were not solved.  This is just over 3%

>unsol acd: 90   mean unsol acd: 9.00

The average depth of the unsolved problems was exactly 9 plies on average

>unsol acn: 14796044   mean unsol acn: 1479604.40

The average nodes examined on the unsolved records was 1.48 million

>unsol acs: 103   mean unsol acs: 10.30

The average time attempted on unsolved records was a fraction over ten seconds

>unsol mean node frequency: 143650.91 Hz

The NPS for unsolved records was about 144K NPS

Crafty has an egtb special help command.
