There could be a reliability trade off here--with the engines needing to last several more races. Cooling issues may be a way of saying posterity and long-term strategy. In future races Merc may be choose to switch on their higher engine modes for a return to normal pace. However, the Honda unit may indeed now have improved efficiency, lowered cooling requirements.

Compared with Max and Honda who ran mode 11 for 30 laps. It's a good sign concerning the cooling and the entire package.
