Hi Astromon! Now that we have data for round 1, I think it's important that we switch back to the round 1 targets and figure out how to improve the results there. This is what round 3 will be.
As to the exact timing of the switch to round 3, I'm not sure exactly when that will happen. The devs who would normally do this are short on time too, (aren't we all :-) ); and you may indeed get some extra time. But I wouldn't count on a major extension.
And don't throw away any unfinished work you have in progress. Before the end of round 3, we should have results back for round 2, and round 4 may use the round 2 oligos again.
