I was able to conclude that cylinder 3 is the only cylinder to misfire and only misfires under high load (i.e. WOT 3rd gear, 2.5k - redline).
I have yet to see a check engine light despite cylinder 3 misfiring for a whole 2.12 seconds in one data log and on many other occasions. I plan on taking a look at my plug and coil pack for cylinder 3 sometime this week.
In the meantime, has anybody experienced this issue before / know how to resolve it?
Any help is appreciated, thank you!

Not enough experience on my end, as I've never had issues with this. But could it be a gap problem? Thought that should cause problems across the whole RPM range I would think. I assume they were all torqued correctly and equally. It would seem that it isn't the plugs that are they issue, but possibly the coil pack for cylinder 3.
