Yup, wanted to confirm here the ~100x in efficacy comes from getting 10x in relevance and 10x in ability (from selecting someone 10x better than the average research scientist).
Regarding the relative value of PhD vs scientist: the model currently values the average scientist at ~10x the average PhD at graduation (which seem broadly consistent with the selectivity of becoming a scientist and likely underrepresents the research impact as measured by citations—the average scientist likely has more than 10x the citation count as the average PhD). Then, the 5 years includes the PhD growing significantly as they gain more research experience, so the earlier years will not be as productive as their final year.
Whether the program recurs likely depends on a few different factors including the results of the first iteration of the program. Assuming things all go well; however, we would be excited to run this again next year.
