Rates by gathering are while you gather at the node: walking to the next node and crafting aren't counted. A gather succeeds as often as the Chance you set for the skill, else 33% of the time (the official wiki's base success rate). They use your gathering stats, set for each skill on the gathering nodes page.

How loot bias works

Your loot bias is the “+X% Rare Loot Chance” on the game's Stats screen. Each drop is picked from a weighted table, and your bias changes every weight in it by the game's own formula:

newWeight = weight + ((bias / 100) - 1) * minWeight * (1 - weight / maxWeight)

Here bias is 100 + X, minWeight is the table's rarest drop and maxWeight its most common. The rarest drop gains X% of itself, so 100 doubles it. The most common gains nothing, and the ones in between gain a little. At 100 on the Alpha Boar, Dice of Karma I goes from 1/861 to 1/434 and the Alpha Tusk Greatbow from 1/172 to 1/144.

A list that holds more than one table, like a crop field's crop and pet food, shows no chance of yours: we don't have data yet on where one table ends. Rifts show none either: we don't have data yet on how loot bias works there.
