Every time an infinite-type resource "ticks" lower it's lowered by that amount.

lower it's lowered

Missing comma, yeah.

The bigger problen is that its unclear what is lowered

From the Example provided on that same page:

{
type = "resource",
name = "crude-oil",
icon = "__base__/graphics/icons/crude-oil.png",
icon_size = 32,
flags = {"placeable-neutral"},
category = "basic-fluid",
order="a-b-a",
infinite = true,
highlight = true,
minimum = 60000,
normal = 300000,
infinite_depletion_amount = 10,

There are two properties described as Must be not 0 when infinite = true. (and thus, related to infinite_depletion_amount): the minimum and the normal. The latter corresponds to the Initial amount that can be observed in the Map Editor.... so it seems like this is reduced by the depletion amount until the value of the former is reached.
I agree that the API docs could be clearer about the meaning of these values, but they do make sense.

The amount of the resource. Seems obvious, but I guess that's just me.

Yes i figured from using it, just the description is confusing

I've reworded the description for the next doc release.
