I'm not saying you're wrong... it's just hard to believe... Are there any datalogs to support that?

Integral (the "I" in PID) is the slowest moving correction of the 3. It's meant to make long-term offsetting changes to compensate for changes in operating conditions/hardware/etc,. It's not intended to catch spikes. That's the "D" or derivative gain. And yes, plenty of datalogs to show this.
