Increasing Cycle Time For Efficiency

I've been facing some issues with very short cycle times with my unit. The unit imo is very oversized for my house. Its a 4 ton in a reasonably well insulated 1350sqft home. I've written a script for my "smart" thermostat that essentially triggers the thermostat into cool mode at 78 and then shuts it off at 72.

My question: Are there any issues I need to worry about in regards to pulling it down 6 degrees per cycle?

Thanks
