Timerift has only 4 treasure chests

Why sometimes after start the timerift it has 6 (or 7 I dont remember) treasure chests, sometimes only 4. 4 treasure chests but in same time, means less rewards. Can you make it consistently? Thanks

Even though there were fewer chests, I never felt disappointment when getting the rewards.

On the other hand, a side by side comparison would solve this mystery.

@Binhjy thank you for reaching out. We’ll discuss this.
