Sorry, off topic, but this means Summer McIntosh has won 25% of Canada's swimming golds. That is crazy. She's not even 20 years old.
Also, almost 1/3 of Canada's swimming medals (20) have come just in the last three cycles. Consider we only got 12 in the 7 cycles before that, including only 1 gold. That brings us to 1984, that's why I stopped there.
For Athletics, almost 25% of medals (17) have come in the last 3 cycles, with almost 1/3 (6) of the golds in that time. We only got 9 medals, and 3 golds in the 7 cycles before that.
This is why Canada's overall medal counts at the SOG were so low historically, we just didn't compete in the sports with the most medals. Now we have some swimmers who can compete for multiple medals, although our track/field output still seems one and done. At least we had De Grasse for a while.
As for rowing, about 20% of the total medals and 50% of their golds came in just 1992 and 1996. Seriously, our rowers won 4 golds in Barcelona, while the entire Team Canada would not win 4 golds all together again until Rio.
