How do Module Reinforcement Packages stack?

As the title says.
In example lets have 2 MRPs, the 30% kind.
How much dmg reduction do I get to the modules:
- 30?
- 60?
- ??
And how will they absorb the dmg:
- They share dmg both
- They get full dmg both
- Only one will get damaged until it runs out, then the other one is the next.
- ??

Same questions for two 60% MRP-s.

Damage resistance is multiplicative (a 60% resist + a 30% resist is 0.4*0.7 is 0.28 damage making it through, or 72% resistance). Only one is damaged until it reaches 0, then the next. I am uncertain as to what determines the order of this...I need to do more testing.

AFAIK, resistances are multiplicative and they die one after the other as Morbad said.

The result is that you can't stack a whole bunch and get immunity until your MRPs are dead because of diminishing returns; moreso if one dies, your resistance goes down. IIRC the most optimal setup is two 60% MRPs and one 30% for that longevity

They provide the percent reduction they say they do in their module description (30% E rated, 60% D rated) to internal modules, and half of that protection to external modules.

They do stack, but do so multiplicatively. In other words having 1 D rated MRP would protect your internals from 60% (0.4x damage multiplier) damage, and externals from 30% (0.7x damage multiplier). Adding a second D rated MRP would mean that your internals are protected from 84% of incoming damage (0.4 x 0.4 = 0.16) and your externals protected from 51% of incomming damage (0.7 x 0.7 = 0.49). Adding a third D rated would mean internals are protected from 93.6% damage, and externals are protected from 65.7% incoming damage. You can of course keep stacking beyond that, but it's not particularly worth it.

Also, they MRPs themselves take the damage they blocked, which means they will break after taking a bit of punishment (E rated has much more durability than D and blocks less damage, so lasts much longer). You can repair them with an AFMU, and doing so is 10 times faster per point of durability, while using the same amount of AFMU ammo than when repairing other modules

So if a MRP absorbs 60%, does that mean the other 40% still gets through and damages the modules? Kind of a let down if so.

Yes, it's not going to protect the modules 100%, but two D rated MRPs protect internals from all but 16% of damage, and externals from all but 49% of damage. So just 2 D rated MRPs mean your internals are effectively 6.25x as durable, and externals are 2.04x as durable

Ah, I get it. Thank you for explaining :)

At least until their integrity runs out, which happens extremely quickly to D rate MRPs.

Still, it's often enough to keep your FSD or thrusters working while you escape.

Yeah, but even just a single 2A AFMU is an extra 700 durability to the MRPs

You buy AFMS refills like limpets or ammo under "Advanced Maintainance" -> "Restock" -> "AFM Unit" at the starport menu.

BTW great explaination, thank you, I had always wondered about that.

If you had the choice, would you rather have 2 MRPs or 1 MRP and 1 AFMU?

I run with 1 MRP and 1 AFMU, but... from the comments here, is it better to just use 2 MRPs if you plan on escaping once shield's go down?

It is really not that hard. I am not too good at it but basically, preset the right screen to modules and the module reinforcement (or canopy) and whenever you are getting low boost past, hotkey to rightscreen, initiate repairs. Done!

Like done in practice here:

Considerably more complex when having to repair and reinable multiple different modules.

Depends on how much protection you need and what slots you can afford to spare.

I find a single D5 + AFMU ideal for my integrity focused Corvette, but for other vessels one or two smaller AFMUs are more suited to what I'm doing and how long I intend to stick around after shields fail.

If you simply want to keep drives, FDS, or PP intact for an escape, multiple smaller MRPs will generally be more beneficial than a single large one.
