## Is there a standard or convention for how refresh/feeding ratios are written?

Forums:

When feeding/refreshing a starter, you often see ratios written like this: 1:2:2, 4:2:1...n:n:n.

Is there a standard or convention for how these ratios are written?

- starter:flour:water
- starter:water:flour
- flour:starter.water
- flour:water:starter
- water:flour:starter
- water:starter:flour
