How can I make it so this spawn script spawns players in the center of the spawn point?

I'm using a free model called "Infinite Obby" which basicly is a script that add's spawn-points with stages. The problem is that when someone spawns it does not spawn them in the center of the spawn point which makes it look bad (In my opinion). I need hep making it so players will spawn in the center of a spawn point like a regular roblox spawn point would.

This is part of the script I think which needs to be edited:

function warpToCheckPoint(torso, cpnum)
	if cpnum == nil then return end
	if torso == nil then return end
	local cp = cpmodel:FindFirstChild(tostring(cpnum))
	if cp ~= nil then
		local chosenCFrame = cp.CFrame	-- Below is the offset
			* CFrame.new(math.random(-cp.Size.X/2,cp.Size.X/2), 2.5, math.random(-cp.Size.Z/2,cp.Size.Z/2))
										-- Above is the offset  ^

		torso.CFrame = chosenCFrame
		wait()
		for k = 1, 10 do
			if torso ~= nil then
				if (torso.Position - cp.Position).magnitude > 3 then
					torso.CFrame = chosenCFrame
				end
				wait()
			end
		end
				
	end
end

This is the whole script:

------------ OPTIONS ------------

local statName = "Stage"			-- You can change this to "Level" or "Chapter" or "Section"
local ModelName = "_CheckPoints"	-- Name of model that stores checkpoint spawnblocks
									-- (You don't HAVE to change this! This is only if you want to.)

local savingEnabled = false		-- Having this set to true will let players save their checkpoint in your game!

local allowDeathReach = false	-- If a player dies but still touches a checkpoint,
								-- It won't count if this is set to false.

local victorySound = true		-- If you want a victory sound for checkpoints, change this to lowercase true.
local victorySoundId = "rbxassetid://12222253"

local cpmodel = game.Workspace:FindFirstChild(ModelName)
local cw = game.Workspace:GetChildren()
for iw = 1, #cw do
	if cw[iw].Name == ModelName and cw[iw] ~= cpmodel then
		local copyc = cw[iw]:GetChildren()
		for icopyc = 1, #copyc do
			copyc[icopyc].Parent = cpmodel
		end
		cw[iw]:Destroy()
	end
end				-- ^ These lines of code should help fix in case  you use multiple _CheckPoint models.


local cpmodelc = cpmodel:GetChildren()
for j = 1, #cpmodelc do
	local cpoint = cpmodelc[j]
	cpoint.Touched:connect(function(hit)

		if hit.Parent == nil then return end
		if hit.Parent:FindFirstChild("Humanoid") then
			local stop = false
			if hit.Parent:FindFirstChild("Humanoid").Health <= 0 and not allowDeathReach then
				stop = true
			end
