Regarding the prerequisites (differential calculus, linear algebra or statistics, programming) do you have any recommended resources for people who have studied these but are a bit rusty and want to revise the content before MLSS? Or a list of concepts or tasks that participants can use to check whether their understanding is at the required level? (e.g. "If you know the concepts X, Y and Z in linear algebra, and can write a program to solve task A and B, then you probably have enough background for MLSS.")
According the numbers quoted ("~45 years, ~$50k income, ~$4,500 per life saved"), isn't it more like 50 lives rather than 100? In the linked GWWC article then it says $2,300 per life saved, not $4,500. I don't know which figure is correct, but it makes a difference by a factor of ~2.
