So according to this, the compass mining 6x s19xp bundle deal they have right now will have a 13 month turn off time
I'm not sure what values you used, but a 13 month shutoff time seems unlikely unless you entered electricity at .65 rather than .065
To make things easy, I used the value of one miner at $13,250, coming online in December 2022, which is about the mid-point of the 6 miners.
Done that way, it never shuts off, but it never breaks even in BTC terms. After 42 months it is at -45% ROI.
