question about loot tables

Question real quick. I have a file called basicguns.json where all items and categories are set to 0 except weapons at 100% and the following items.

machete	20
longsword	25
mace	25
wooden spear	80
stone spear	60
Knife	15
Bone knife	40
Bone club	30
salvaged sword	25
salvaged cleaver	25
crossbow	10
bow	25
eoka pistol	50
revolver	10
semi auto pistol	10
nailgun	30
double barrel	10
waterpipe	25

and i have it set to spawn 0-2 (because for some reason 0-1 never spawns anything)

,
    "crate_normal_2": {
      "enabled": true,
      "lootTable": "basicguns",
      "maxItems": 2,
      "minItems": 0,
      "gunsWithAmmo": true,
      "noGuns": false,
      "MaxBps": 0,
      "WaterPreFillPercent": 20,
      "ClearContainerFirst": false
    }

what is the percentage of the 0-2 items spawning? it seems it's very high, and if so I'd like to add a "blank" item essentially to cut down the spawn count, but when it does it selects from the above list at those pick numbers. it doesn't seem to matter if the weapons category is 5% or 100%, it still only picks from that category since all the others are 0.

i'd basically like to set a percentage that says "15% change of spawning an item, if yes, pick from the above list with those pick counts". can this be done with this plugin?

actually, i think it may work for me if i set the item count to min 0, max 1, but i get an error saying it can't find the item.

If you'd be able to allow 0 count to "spawn", that might work for my situation.

"Just for clarity, the probability settings aren't percentages.
They're arbitrary numbers, balanced against each other.
That means there no maximum, and no fixed scale."

yeah, thats why i called them "pick numbers", basically a lottery with higher numbers getting a higher chance of getting picked like the 1 vs 9 exampled you used.

so there is no way to spawn 0-1 item, so that there is some chance of even if the item is picked, you get 0 of it?
