Well, first of all im glad to read so many users to express their happiness for their countrys performances but, in my case, im in the group of MHSN (but stronger), my country pass for 3 G and 1 S in Rio to 1 S and 2 B, with 177 athletes (its true, 7 teams), we did exactly the same performance in the medal table like San Marino with only 5 athletes......
Of course there are particulars reasons of any athlete and sport but in general reasons i see: 1) clearly less budget than Rio for desicion of the last goverment and being continue with the current, 2) The goverment forbidden for months to get out from our homes and the athltes cant train, the swimmer Pignatiello of 800/1500 meter trains for months in the 2 m swimming pool of their own house and Suarez from rowing was close to go to jail for train ALONE in a river, for say some examples and 3) dont exist a good renovation, we have the same "old glorys" to try to be medallist again, many retired after this games and the yourh olympic games of Buenos Aires 2018 are clearly wasted, only Pignatiello (if i dont remember bad) was the only one who was there and being in this olympics.
I dont believe it will be a an important decision to make the situation better, so im not optimistic for Paris.
