Thanks for considering credit allocation for dead-end units. All of mine seem to have failed in the first 30 seconds so I didn't expect any but in the case where more substantial computing time has been invested lack of due credit could skew people away from certain batches.

Rosetta currently gives credit for all failed tasks, so you shouldn't see a problem there. If the task failed after 30 seconds you will earn 30 seconds of credit. A task that ran for 2 hours and then failed will earn 2 hours of credit.

As I mentioned above, "There is an automatic script that runs each night to award credit to tasks that ended in an error. Because the script is a modification to the normal BOINC process the granted credit only shows up on the task page."
