Lunar Rifts Not Spawning More Crystals sometimes

Crystal spawns are weird. The 0.75-1.25 day timer doesn't actually spawn crystals, it just schedules a new crystal set to be spawned 1 - 2.167 days from the time that timer starts (Changes during phase 3 to 0 - 5.33 days). There's a max of 1 set of crystals during phase 2 and 3 sets during phase 3. It looks like it only queues crystal sets up to this max, but I'm not positive that always holds true.

I did a data set on this recently (this was update 572130, before the beta):

(This is in day units. Testing methodology was getting TheWorld's age debug string every time a crystal spawned, timer stopped, or phase changed. Note the orange sections don't count for scheduling crystal spawns because I didn't mine them all in time.)

I'm getting 1 - 2.167 and 0 - 5.33 from an online lua compiler interpreting this code, which is a re-arranged version of the code from lunarrift_portal.lua

Spoiler

-- Code is taken from lunarrift_portal.lua

local TILE_SCALE = 4
local MIN_CRYSTAL_DISTANCE = 3.0
local MAX_CRYSTAL_DISTANCE_BY_STAGE = {0.0, 6.5, 22.5}
local CRYSTALS_PER_RING = 4
local TERRAFORM_DELAY = (4.0 * 480) / 3

-- These functions return time_delay with math.random() being substituted for 0 or 1
local function calcMinTime(phase)
    return math.max(0, ((MIN_CRYSTAL_DISTANCE + math.sqrt(0)*(MAX_CRYSTAL_DISTANCE_BY_STAGE[phase] - MIN_CRYSTAL_DISTANCE) - (MAX_CRYSTAL_DISTANCE_BY_STAGE[phase - 1] or 0)) / TILE_SCALE) * TERRAFORM_DELAY)
end
local function calcMaxTime(phase)
    return math.max(0, ((MIN_CRYSTAL_DISTANCE + math.sqrt(1)*(MAX_CRYSTAL_DISTANCE_BY_STAGE[phase] - MIN_CRYSTAL_DISTANCE) - (MAX_CRYSTAL_DISTANCE_BY_STAGE[phase - 1] or 0)) / TILE_SCALE) * TERRAFORM_DELAY)
end

for s = 1, 3 do -- for phases 1-3, print minimum and maximum time for crystals to spawn.
    print("Stage: " .. s)
    print("Minimum time until crystals spawn: " .. calcMinTime(s) .. " seconds or " .. calcMinTime(s) / 480 .. " days")
    print("Maximum time until crystals spawn: " .. calcMaxTime(s) .. " seconds or " .. calcMaxTime(s)  / 480 .. " days")
    if(calcMaxTime(s) - calcMinTime(s) < 0) then
        print("Impossible range, so crystals can't spawn during this phase.")
    end
    print()
end

Corrected phase 3 spawn time and added code for spawn delay
