Olympic medal results are conventionally listed according to the number of gold medals, with silver and bronze medals only being considered if there is a tie. We can sort the medal table in this way with a custom sorting phrase:
|
|
|
|
{**}To decide which number is the ranked medal comparison of (T - table name) rows (X - a number) and (Y - a number) (this is ranked medal comparison):
|
|
if gold in row Y of T > gold in row X of T:
|
|
decide on 1;
|
|
if gold in row Y of T < gold in row X of T:
|
|
decide on -1;
|
|
if silver in row Y of T > silver in row X of T:
|
|
decide on 1;
|
|
if silver in row Y of T < silver in row X of T:
|
|
decide on -1;
|
|
if bronze in row Y of T > bronze in row X of T:
|
|
decide on 1;
|
|
if bronze in row Y of T < bronze in row X of T:
|
|
decide on -1;
|
|
decide on 0;
|

But this isn't great for Italy - are France's two more silver medals really so much more significant than Italy's nine more bronze medals? Let's sort this table by the total number of medals, so that Italy can sit in proud seventh place.
|
|
|
|
{**}To decide which number is the total medal comparison of (T - table name) rows (X - a number) and (Y - a number) (this is total medal comparison):
|
|
choose row X in T;
|
|
let total X be the gold entry + silver entry + bronze entry;
|
|
choose row Y in T;
|
|
let total Y be the gold entry + silver entry + bronze entry;
|
|
decide on total Y - total X;
|
|
