Does this timing advance look right?

Just got a few engine parameters while driving, I wonder if the timing advance makes sense? I get pinging under heavier acceleration in lower gear, the fuel may be for something (87) but I wonder if there may be something else

I see 25.9% load but what is the RPM?
11 deg is not too bad for that load and boost. Richer mixture burns faster and needs less advance. Lower octane could also be stepping into some retard for knock.

Advance is complex on a turbo car. I’ve notived the second boost comes on the ECU slams the spark back to near TDC from its max of 30-33 BTDC , monitoring by scanner

I’ll try to run some data in a trip today on my T5 but the R cars don’t like it when I drive off and leave them, they get scaRed alone.

The rps is the Revs cadran at the left upper corner. It's the non turbo engine.

I couldn't get the youtube to play yesterday. I see in the whole RPM number in the video this morning. Idling normal value is 10-12 degrees. Timing at idle is also variable due to it being used as another way to control idle speed so it can drop to 6 or 7 briefly if speed goes up while idling. Octane of fuel would not be a factor idling as likelihood of knock at idle is negligible.
Intake PSI is apparently absolute value making that sommething like 18 inches vacuum. What app is being used?

It's with Torque Lite on Android. I've also got comments on the Intake pressure being too high at idle, could this be an intake pressure sensor fault? The PCV is new with good vacuum at the fill cap.
