Summer time in relation to EV share

A perhaps somewhat curious observation: I switched my 2024 Yaris to summer time on Sunday in the menu. Since then, the EV share (automatically by system, not manually by EV button) has gone up noticeably. The last months, even during the high temperatures a few weeks ago, the EV share according to the display was at most by 50%, now after the conversion at once again at 80%. The consumption according to on-board computer declined from just under 4 liters to 3.4 liters. And no, that’s NOT April’s joke. If that’s not a big coincidence that the system on the same routes and at unchanged temperatures at once changes the EV share significantly upwards due to any changed factors that I didn’t recognize, it can actually only be due to the switch to summer time. However, that would be an almost curious thing in fact. Should the system actually be aware during the summer time m I was also surprised that despite 20° in March, the car often ran the burner, while last autumn the EV share was so high in the same circumstances.
