"Time to Temperature"

Sorry, forgot to say I have a Google Nest 3.7 thermostat.

What does everyone think about that "Peak Time" thing? I don't like it because when the time is up and it is supposed to set the temp back to what it was, it always goes either too high or too low.

Like we have ours set on Heat/Cool. It's set to 65/74. Peak Time sets it from 3pm-9pm at 64/75. When it's 9pm, I check because I'm freezing and it says 73. If I leave it alone or forget to change it back, within a few days it will get all the way to 72 or 71 for the AC. I have to constantly go and turn off the Peak Time and put it back on what it was. I finally got tired of it and just turned off "Time to Temperature" settings on my Nest app.

Does it actually help anything? And if so, how do I fix it to where it puts the temp back on what it was set on when it's finished?
