B58 misfire on 2 cylinders during/after low fuel!?? Fuel quality!? something else!?

Stage 2+ RON 98.
No E whatsoever now for the sake of troubleshooting. The timing corrections will clear once I add a bit of E as I normally do. Actually quite pleased how it looks like without any E.
Anything else?

Feedback for those who may experience this in the future:

After a full tank (pure gasoline, no E) of driving (both short and long trips) and intentional dropping down to fuel reserve again (went down to 4L of fuel in the tank before I refilled) - no sign of the misfires, fortunately!
Hope it was some incidental air sucked in by the fuel system! 🤞🏼
