Why does the growtime of marble shrub in code differ from that of wiki explained?

[dish-order man]

My friends, recently i started to read the code of some items and there is a question i met about the growtime of marble shrub.
 

In the file [marbleshrub.lua], there goes:

local GROWTH_STAGES =
{
    {
        time = function(inst) return GetRandomWithVariance(TUNING.MARBLESHRUB_GROW_TIME[1].base, TUNING.MARBLESHRUB_GROW_TIME[1].random) end,
        fn = function(inst) SetGrowth(inst) end,
        growfn = function(inst) DoGrow(inst) end,
    },
    {
        time = function(inst) return GetRandomWithVariance(TUNING.MARBLESHRUB_GROW_TIME[2].base, TUNING.MARBLESHRUB_GROW_TIME[2].random) end,
        fn = function(inst) SetGrowth(inst) end,
        growfn = function(inst) DoGrow(inst) end,
    },
    {
        time = function(inst) return GetRandomWithVariance(TUNING.MARBLESHRUB_GROW_TIME[3].base, TUNING.MARBLESHRUB_GROW_TIME[3].random) end,
        fn = function(inst) SetGrowth(inst) end,
        growfn = function(inst) DoGrow(inst) end,
    },
}

the data of the 'time' in this code is:

        MARBLESHRUB_GROW_TIME =
        {
            {base=9.0*day_time, random=1.0*day_time}, --short
            {base=9.0*day_time, random=1.0*day_time}, --normal
            {base=9.0*day_time, random=1.0*day_time}, --tall
        },

In the file [util.lua], function GetRandomWithVariance like below:

function GetRandomWithVariance(baseval, randomval)
    return baseval + (math.random()*2*randomval - randomval)
end

 

 

From these codes I think the growtime of marble shrub should be 9±1 days. But I check it on wiki, it is far from what I think:

Quote

It takes 2.5-5 minutes for a Marble Sprout to grow to Stage 1, 5-6.25 days from Stage 1 to Stage 2, 5-6.25 days from Stage 2 to Stage 3, 5-6.25 days from Stage 3 to Stage 1. Growing is not affected by Seasons.

 

Why the growtime of marble shrub being 5-6.25 days? Is there more factor to effect this time that i have not noticed?

 

I'm confused about it now, anybody explain this to me? many thanks!!!!

From tuning.lua:

local seg_time = 30
local day_segs = 10
local day_time = seg_time * day_segs

The day_time variable is not the duration of an in-game day (which is 480 seconds). It is the standard length of the "day" portion of an in-game day AKA 300 seconds.

At each stage, the code calls GetRandomWithVariance(2700, 300), which returns

2400 + math.random()*600

Minimum value is 2400 =  5 days.

Maximum value is 3000 = 6.25 days.

many thanks!!!! Thanks to ur explanation, I found the definition of the this data in [tuning.lua].

    local seg_time = 30
    local total_day_time = seg_time*16

    local day_segs = 10
    local dusk_segs = 4
    local night_segs = 2

    --default day composition. changes in winter, etc
    local day_time = seg_time * day_segs
    local dusk_time = seg_time * dusk_segs
    local night_time = seg_time * night_segs

I used to think that the time of day,dusk and night should be a changeble data, so I never thought that 'day_time'  being a 10 seg_time data. It is a useful knowledge, thanks!
