This seems to be very RNG dependant and/or my parts have the wrong combination of stats.
I have 16 submarines (on main and alts), half of them on your setup and half on other setups, I didn't get any slab at all. I even tried a lot of setups, and got the results that it has VERY low drop rate, and there's no perfect setup for it.
1st: The submarine has to face normal weather in Neolith Island (which has a low RNG rate), because no matter the setup you have, the submarine still gets "exploratory capability may be significantly hindered" on bad weather. (I tried max surveillance, max Favor, even max retrieval, and even max possible mix of surveillance and Favor) (I even tried sending the submarine from other sectors to Neolith Island, I got different weather conditions, but still no slab)

2nd: if you you get a good RNG with weather (no bad weather), you still have to face the low drop rate of the slab.
