For what it’s worth I’ve addressed this issue a bit here. A relevant quote from it:
If we include experiences of experiences of experiences in our ontology rather than compressing them into experiences of experiences, thus making a systems-level demand for ontological complexity, we can understand contentment as an experience of happiness towards all experiences of experiences and use it to direct tranquilist axiological reasoning. In this way contentment wraps happy and sad experiences in an experience of happiness, making it of a different type and avoiding apparent contradiction by adding happiness to rather than changing the original experience from pleasure or suffering.
Having deconstructed contentment and understood tranquilism precisely, it appears my original concerns about feedback being suffering were confused because if suffering, a negative valence experience, is something we can be content with, then in this context suffering must be an experience of experience and thus feedback cannot necessarily be suffering because feedback can exist as a direct experience not just a meta-experience.
