If having a high temperature delta was a concern everyone in Texas would be dead by now.
I set my thermostat to 65F in August. My house is at 67F right now and it's 81F outside (at 7AM). We're still catching up from yesterday. I don't see the point in allowing the condensing unit to shut off when it's this hot and humid out. You are just giving the angry super Mario sun a head start when you let it turn off in the morning. The temperature in my house will still rise to 74-75F with this unit running non stop. The forecast for today is approximately 100F.
At some point, the cost of electricity becomes constant (100% duty cycle). You can't run the air conditioner more than all the time. It makes the equipment last a lot longer when it's not being cycled every 10-15 minutes. It can be cheaper to just keep things brutally cold given the relatively affordable electric rates. $300 capacitor replacement can buy a lot of kilowatt hours in the ercot and entergy markets. Short cycling a compressor with high pressure and you could be replacing one every other year.
If any of this sounds offensive, I would invite the offended party to join me for lunch in downtown Houston or Galveston sometime this week.
