The failures so far may just be random chance. We'll only know after some have finished.

One that I picked up had failed after 2 minutes, but is nearly half an hour into it on my computer.

43 of batch 789 have completed when I looked yesterday.

Now at 115 completed vs 901 failed for 789.

The 789 that I picked up produced it's first zip at 6.4%, 4 hours 22 minutes.
I've stopped it again, to complete the original 4.

Figures on batch 789 now at
Success: 281 (3%)
Fails: 1045 (12%)
Hard Fail: 5 (0%)
Running: 5381 (63%)
Unsent: 2912 (34%)

The numbers of 790 are still low enough that the percentages don't mean a lot except perhaps fails now up to 9 %.

I now have four successes on my 789's, after three failures. And several more are now running past the point of the failures. So I think they are getting better. (It is similar with the 790's thus far.)

I will check on the batch statistics again tomorrow and see how things are progressing. It will be interesting to see if the failures all turn into hard failures i.e. all three attempts fail.

I've got four 789s at various stages between 2.5% and 29% completed on my i5. Fingers crossed.
