Refer to posts by uplinger on the batch numbering. The sizes will be 3 (that we know now), each either target01, target02 and target03 sized, with subs starting with 001 through 999 i.e.

target01-00100001 through target01-999999999

Receiving today a target01, 1 out of 75 suggests it's a repair job. The Result Status page WU quorum detail has the definitive answer.

Sek, I am afraid to inform you but that information is already out of date :( It is my fault for not updating my previous post...but the new scheme is like this. BBBBBWWWR. so, it's more like 000010010. Where 00001 is the batch number. 001 is the work unit and the remaining 0 is actually a random number between 0 and 9. The researchers have asked us to instead of making 1,000,000 work units per target to make up to 99,999,999. So we changed it to handle up to 99,999,999 just in case :). Target03 is on hold right now as we are working on getting all the results that have finished thus far back to the researchers. Already over 217,000 results (217 batches) have been completed. :) So we will be on target02 for longer.

As for the original question, we shall not see target01 again. There may be smaller work units in the future, but this I do not know.

Hope this helps,

Try updating now. I got 14 target1 (_1) WU today, on a Q9650 @3.0 GHz
