BAP, one indeed should be very careful about not abandoning WU's, it's bad for the science. That is in fact why the harsh penalty is there, so that people just don't go dumping ones they don't happen to like. The penalty, for the record, is incurred when an 80% completion rate is violated to the downside. I don't know if it's a moving average, I've always just assumed it's an overall average.
That having been said, yes, nice action there now that you're out of the penalty.
