Update: I have now read the email.
For the context Geoff gives, I think these standards make sense. Although, I would argue that if you could meet the standards with the 24 kg bells you could handle all of the examples that he cites (e.g., chopping wood, moving, pushing your friend to the ground outrunning your friend when being chased by a bear). If you could meet the standards with a 32 kg bell, you are a beast in my book.
I will add that snatching a 32 kg bell for 100 reps in 10 mins sounds impossible to me currently. I am running a modified version of DFW with the 24 kg bells. My best has been ladders of 2-3-5 for a total of 35 reps in the C&P and DFSQ in 30 mins. Realistically, I could reach 10 sets of 5 in a few months, especially if I am "only" doing one of the exercises in 20 mins. However, I still feel really uncomfortable snatching the 24 kg. The most snatches I have done with the 24 kg is 3 sets of 10 reps (5 on each hand) and that was a struggle. I'm not even sure I could meet the snatch standard the 20kg bell. I am fairly confident I could do the 16 kg, but I have not tested.
It also seems to me that C&P and DFSQ are more closely related to strength, where snatching is more closely related to power and cardiovascular capabilities. I think an interesting twist would be to condense the time frame for the snatch standard, a la the RKC/HKC snatch test. Goals 1-3 would remain unchanged. For goal 4, keep the 28 kg for C&P and DFSQ, but snatch the 24 kg 100 reps in 5 mins. And the final level could keep the 32 kg for the grinds, but the snatch standard would be 200 reps in 10 mins with the 24 kg.
