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:
Hope this clarifies the issue.
That is a very good point and one we hadn't really thought of.
The agreements don't specify whether the tonnage commitment refers to live weight equivalent (i.e. whole shrimp) or headless peeled weight. My sense is that, from context, producers are interpreting it as the former. We will think about whether to clarify this going forward in the agreements or whether we prefer the ambiguity as it might work in our favour.
Regarding monitoring adherence, as of right now, we feel our most sensible approach is to base it on the representations that the producers will be making to their buyers. Defaulting obligations to SWP seems pretty innocuous for producers but defaulting or misleading their buyers is a whole different ballgame and one that could cost them their business. This is the reason why we always try to have the buyers being party to the agreements stating that they will prioritise stunned shrimp.
Thanks for your interest in shrimp welfare and I hope this addresses your questions.
First and foremost, I want to express my deep gratitude to @MHR, @MarcusAbramovitch and @Aaron Bergman for kickstarting this discussion in the EA Forum. As mentioned in the post, this is currently SWP’s most cost-effective programme and one that we are very keen to continue to scale in the coming few years. To achieve that, we expect to rely on the support of our existing donors but also on that of the EA Community at large.
Second, we couldn’t have asked for a better way to get the conversation started than for a third party to look at our programme in such depth and to put it to the community for consideration in an impartial way.
Finally, I want it to be clear that my comments should not be interpreted as a negative reaction to the post but quite the opposite. It would have been nearly impossible to do a better job at portraying and evaluating our programme without further ‘insider intel’ which I hope to provide a bit of here.
Thank you!
In the coming days, we might have some more feedback on the specific assumptions made in the post but I wanted to make some clarifications as early as possible:

Just a couple of points on the original comment about AIM:
Regarding SWP not doing what CE originally proposed we do: I've mentioned this openly at least in a couple of interviews (80K, HILTLS). My goal was not to demerit AIM's research but rather to say that there is so much one can learn from desktop research in a low-evidence space such as animal welfare and it is the role of the founding team to explore the different permutations and see what sticks
I apologise in advance for not engaging further with the comments about AIM / animal movement but we are very (human) resources constrained at SWP and the case in favour of AIM has been sufficiently established IMO
Regarding the discussion between @James Özden and @MichaelStJules, you are both right to some extent:
