The short answer
Not yet. Conntal is new, and a retention or time-to-fill figure computed across a handful of placements would be noise presented as evidence. We will publish them when the sample supports it, together with how they are measured.
Not yet — and we would rather say that than publish a number we cannot stand behind.
Conntal is a new firm. A retention rate or time-to-fill average computed across a small number of placements is noise wearing the costume of evidence. When the sample supports a figure we will publish it along with the method — retention measured at what horizon, counted how, across how many placements — because a statistic without its method is exactly the kind of unverifiable claim this site exists to avoid.
In the meantime, the checkable claim we do make is the screen itself. It is published, and you can judge it.
