Apply a "fuzz factor" to prevent cards sticking together

Later versions of the SuperMemo algorithm, and newer versions of the Anki scheduler apply a small “fuzz factor” which provides a little bit of randomisation to intervals. This prevents cards created on the same day, and given the same grade, from always sticking together.

For reference: Studying - Anki Manual

This also has a side benefit of helping this issue: Bury (automatically) other cloze cards on the same rem

Automatically burying clozes on the same rem is still an important feature in its own right, but by introducing a fuzz factor you at least make sure to space out related clozes in the future (as well as image occlusions and bidirectional cards).
