Query: Not very accurate so what's the point?

The indoor thermometer is fairly accurate but it's not very quick to change. The manual states that it's updated every 10 seconds but I've found it to be more like 30 minutes.The outdoor portion is even worse. It takes hours to adjust its temperature and so it's regularly off by 10-20 degrees. The other night it was 84 (by another thermometer) but the outdoor reading said 107! A couple hours later it did come back down to the correct temp but that really doesn't matter does it. It needs to be accurate in real time.
