Hamilton says ditching the Ferrari simulator saved his season — anyone else find that wild?

The detail that Hamilton stopped using Ferrari's simulator ahead of the Canadian GP, and credits that decision with turning his form around massively, is one of the stranger storylines of the season so far. Simulators are supposed to be an unambiguous advantage — more laps, more setup iterations, zero risk. For a seven-time champion to conclude his was actively working against him says something about how differently his driving style translates to a rig versus the real car, or maybe about trust in the correlation data itself. Does anyone have more detail on what specifically wasn't working for him?
