Overall i would consider most of the predictions pretty good, but i am not sure about the following predictions for overall medals:
- 3.45 medals for Sweden: Unless i am forgetting something, their absolute best case would be 4 medals for Sjöstrom (50 free, 100 free, 200 free, 100 fly). She is pretty much a lock in the 100 fly, but it isn't even certain that she will compete in the 200 free and in the 50 free and especially the 100 free she isn't a lock for a medal. I would consider 2.5 medals a more realistic prediction.
- 1.90 medals for France: Right now i would say 1 medal in total seems to be the most realistic prediction for them, probably for Manaudou in the 50 free (although he will have to beat at least two out of Fratus, Dressel, Morozov and Proud). They have other medal contenders (men's open water, men's 800 free), but i don't think that those 3 (the two mentioned before + Manaudou) combined are likely to win 2 (1.90 to be precise) medals.
- 0.74 medals for South Africa: I think you are underrating their medal chances. Le Clos (100 fly + 200 fly) and Schoenmaker (200 breast) should combine for an expected medal count of around 1.50 in my opinion.
- 0.69 medals for Lithuania: I think right now Rapsys has to be considered the favorite for gold in the 200 free and i don't see 3 other guys who are more likely to medal in the 400 free right now. I would have them at 1.25 medals or something like that.
- 5.25 medals for Hungary: 5 medals realistically seems to be the best case for them in my opinion (2 x men's 200 fly, women's 200 IM, women's 400 IM, women's 200 fly). Kesely (400 free), Hosszu (200 back) and Milak (100 fly) have outside chances for more medals, but on the other hand 2 medals in men's 200 fly and a medal in women's 200 fly are far from certain. I would say their expected number of medals is closer to 4.50.
- 6.32 medals for Canada: 7.50 seems more realistic in my opinion. 3 medals in the relays on the women's side are almost a lock (at least the 2 medals in the 400 free relay and the medley relay), the same is true for a medal in women's 100 fly and then you also have (very) good medal chances in women's 100 free, women's 200 free, women's 200 breast, women's 100 back, women's 200 back, women's 200 IM and women's 400 IM.
- 7.91 medals for Italy: I really don't see how Italy should win 8 medals? Men's 400 free, men's 800 free, men's 1500 free, women's 200 free, women's 800 free, women's 1500 free, women's 200 back. Those medals aren't all a lock (especially men's 400 free, women's 200 free, women's 200 back), but of course on the other hand they have (outside) chances in other events like women's open water and men's 100 breast. Overall i would consider something like 6.50 or 7.00 a more realistic value.
In the end it is still a long time until the olympics and i am sure a lot of things will change until then, so probably it is still too early for predictions like that to be taken too seriously, although of course it will be interesting to compare the actual medal table to your predictions. When/how often (if at all) will you update your predictions?
