MOSFET rating/derating data

I had a look inside my new Gen 2 Stealth Fighter's controller and see these MOSFETs. Magnachip MDP10N027
I look up the data sheet and see a load of data points.
2 questions.

Seems these are 120A FETs. 18 fet controller = 3 FETs in parallel = 360A
So does that mean my controllers absolute maximum phase current is 360A? Any derating?

What other points of data are of interest to me? Resistance? (2.8mohm) Voltage? (100V)

Oooff! I don't know that I would push it that hard. FETs in parallel can certainly handle more power but you have to figure there is some RdsON resistance and that is not going to be 'perfect' across all FETs. So one is going to be handling more power than the others. Plus, that max current is probably only going to be available under a certain set of thermal conditions, frequency domain and a certain set of gate drive conditions... which may or may not be met by your controller. Just ballparking I'd say 1/2 or 2/3 the ratings might be a good 'redline'...unless you're just looking to push it to the ragged edge.

Honestly I'm just trying to build understanding.
Elsewhere I've asked about shunt mods and other ways to increase torque.
One thing mentioned is "have a look at your FETs and see how far you can push"
So I looked at FETs and data and now wondering how that could be applied.

So approximately 40% derating is what you believe?

Mostly academic I'm not looking to actually push to the edge. Kinda hyper focused on the subject ATM

For understanding part, the datasheet should have a bunch of graphs tracking performance vs various parameters. The more of those parameters you can pinpoint, the more you can refine the performance expectation.

The trouble I typically run into as an amateur hobbyist is that I can spend hours/days measuring, tracking, refining those parameters or for a couple bucks more, I can just get a mosfet with double the ratings and stay on the cautious side. But if on the manufacturing side, a couple bucks times 6,12 or 18+ mosfets per unit, times thousands of units ...starts to add up. So they are willing to push things more.
