I actually don’t think that we would be overestimating. Your original intuition was correct.
The way it works in practice is that buyers ask for a certain size of shrimp (e.g. 14g). This is always quoted in live weight equivalent. Then comes the second criterion of being peeled, etc. This normally means that somewhere between 35-50% of the weight is lost. If we just use 50% for simplicity purposes, there are two possible scenarios:
The producer assumes the agreement was for live weight equivalent and there is no change to our numbers, OR
The producer assumes that it refers to the volume actually sold. Because each shrimp weighs 50% less, we need to gross up our numbers by that factor, i.e. the number of individual shrimps would be 2x our estimate

Hope this clarifies the issue.
