When doing "sulfur.ore": "2/2" in "CustomRateMultResource" does this mean sulfur will be 2x?

What do settings like 3/4 mean? That it's only 3 quarter of the vanilla amount?

From plugin description:

Format for individual items multipliers:"short_prefab_name": "day_multiplier/night_multiplier"where / - separator

Format for individual resource gather tools multipliers:"short_prefab_name": "day_multiplier/night_multiplier"where / - separator

Note: Resource gather tools multipliers override all other resource gather multipliers include bonus!
