How to change the distance the doors move apart?

Got this script from a sliding door I found, but being me I don't know most of what is going on in the script. I just need to know how and where to change the distance the doors move apart in the script.

door = script.Parent
door1 = door.Door1
door2 = door.Door2
button = door.Button
isopen = door.IsOpen
debounce = door.Debounce

button.ClickDetector.MouseClick:connect(function()
    if (debounce.Value == false) then
        if (isopen.Value == true) then
            isopen.Value = false
        elseif (isopen.Value == false) then
            isopen.Value = true
        end
        button.BrickColor = BrickColor.new("Black")
    end
end)

isopen.Changed:connect(function()
    if (debounce.Value == false) then
        debounce.Value = true
        if (isopen.Value == true) then
            for i=1, 190 do
                door1.CFrame = door1.CFrame * CFrame.new(-0.1,0,0)
                door2.CFrame = door2.CFrame * CFrame.new(0.1,0,0)
                wait()
            end
            debounce.Value = false
            button.BrickColor = BrickColor.new("Bright red")
            return
        end
        if (isopen.Value == false) then
            for i=1, 190 do
                door1.CFrame = door1.CFrame * CFrame.new(0.1,0,0)
                door2.CFrame = door2.CFrame * CFrame.new(-0.1,0,0)
                wait()
            end
            debounce.Value = false
            button.BrickColor = BrickColor.new("Bright green")
            return
        end
    end
end)
