ModIQ is designed as follows :
Think of it like the Medtronic AutoMode works... every night at midnight, it (appears) to compare how the last 24hrs went compared to previous days and internally recalculates what rates to use for the next 24 hours where it will then recalculate any modifications required
As we know the Tandem pump works off your programmed rates when you are within range (the range varies according to what activity mode - Normal, Sleep, Exercise) and when you are predicted to go outside, and how far outside that range, will modify the programmed rates - the less variation it needs to make, clearly the simpler it will be should it later need to make a variation
