Sleep vs Idle

Just wondering if anyone else has thought about this, or might have any insights.

I have two Teslas, a Y and a 3, on TeslaFI. I notice that the night time sleep vs idle ratio for both cars fluctuates from around sleep 95% : idle 5% to sleep 70% : idle 30%.

Does that sound right to you? Is there anything special I should be looking for? It seems to me that (all things being equal), the more sleep, the better. But I am not sure. I know there are some sleep adjustments in TeslaFi – do people on this forum generally leave those those alone, or has anyone tried to adjust them to get more sleep?

Thanks.
