Thanks, so you suggest me to flash my ecu again, then to log afterwards to see if this value starts with 0.7 or 1?

2) No. Likely a mistake in the logging. If you flash your ecu again does it start at 1 or .7? If so, your ECU is detecting a lot of knock and reducing timing (logging good, engine bad). If after flashing the adv multiplier starts at 0, then you definitely have a logging issue (logging bad, engine ???).

Hope that helps.
