We getting close. The drop out rate IS part of the mortality. Just as with a pole that you release with or one hits and gets away to the ones that look OK but in the end fail to spawn successfully. The release moralities and drop outs are part of the same number so in the model it is accounted for. SB the thing I think it is about is simply that the number be it what you call is way underestimating moralities and staff knows it as do the RECS and neters both QIN & NT. Nobody seems to care much outside a few people.
