The Retention Ceiling
Retention is capped at 100 percent and cannot do anything else. It buys a longer window. What happens inside the window is a separate question with no cap on it.
What it is not
Not a reason to stop working on retention.
Where it was staked
-
Gross retention cannot exceed one hundred percent. So perfect retention is not slow growth, it is flat. Which leaves exactly two sources of growth, and only one of them keeps working after you stop paying for it.
