I don't find the new version to be good either.

Let's start by figuring out what is meant and then describe that instead of patching it. The issue is that the table-output is not continuously differentiable (except when splines are selected in the models that allow it) - but the events ensure that the integrator does not see this.

Thus I would write something like:

"The table is implemented in a numerically sound way by generating time events at interval boundaries, this generates continuously differentiable values for the integrator."

FIXED in 7e733dc using a slight variation of Hans' proposal:

- , in order to not integrate over a discontinuity or not differentiable points.
+ . This generates continuously differentiable values for the integrator.
