This is pretty interesting (the high level conclusion, I do not claim to understand more). I've recently done a bit of pretty light research on the sense of smell (in the context of AR/VR) and it seems like smell can "transport you across time/space" faster than other senses. Might be an interesting follow up. If one can speed up recent events for quick recall/learning naturally maybe smell can somehow be used to speed up the going back in time aspect (some smell trigger to make the event feel recent+the 10-20x speedup combined)?
