[2.0.72] Recipe output tooltip mismatches actual behavior under some configuration

[cyx2020f]

I made a recipe to output iron plates with in range 0 ~ 100 but 50 are ignored by productivity

Code: Select all

data:extend {
    {
        type = "recipe",
        name = "test-tooltip-error",
        results = {
            { type = "item", name = "iron-plate", amount_min = 0, amount_max = 100, ignored_by_productivity = 50 }
        },
        allow_productivity = true
    }
}

default energy_required is 0.5.

When crafting, it gives 0 ~ 100 iron plates every time the crafting progress finishes and it gives 0 ~ 50 iron plates at ~50% probability every productivity progress finishes, but the tooltip displays as if it thinks that 50 > 0 so no extra products can be produced.

So a assembler 3 crafts 125 iron plates per second. When inserting 4 legendary productivity modules, 0.4(speed multiplier) * 1.25 (base speed) *50 (average output per craft)/0.5(craft time)=50 (base output) + 0.4(speed_multiplier)*1.25(base speed)*1(productivity bonus)*25(average extra output)*0.5(extra output probability)/0.5(craft time)=12.5,total is 62.5 /s (Observed 3.7k / min), but the tooltip says 50 (49.9 due to rounding error)

(The productivity and crafting cycle are misaligned so there are no buffer problems)

Thanks for the report. I did a lot of checks and verified that the numbers were incorrect when item product uses ignored_by_productivity. Based on my computation, in this specific case it should be showing average production of 62.6237 items per second (50 of normal product and 12.6237 of bonus product). Since fix for this is quite complex, i decided to fix this issue for 2.1.
