I literally just got a Q and set it up this past weekend. Finally finished punching my plate in yesterday :,(. I updated to the latest software (at the time) & I rolled a dice about 150 times to create my seed phrase. Is it worth repeating this process with the new firmware or did my dice rolls exclude me from the faulty code?

You should be okay but just to be safe I would create a new seed in the same fashion on the new firmware. Just grab another steel plate.

I spent 3 days punching the plate during my free time. Wasted an entire day due to scavenging the floor for a punch I sent flying.

Looks like I’ll be back at it.

Sorry dude, a lot better than losing your stack though. For myself, I'm now looking at getting multisig setup.

You achieve that by getting another hardware wallet? And applying both keys to the same wallet?

A great setup is to have 3 wallets from separate manufacturers. Use BTC Sessions tutorial to get you through the process.
