After some reflection I have the following problems with this bird.

1. Why is it necessary?  vt tables taken for different load conditions should give you sufficient insight into the multi stage behavior. And if the data covers the load range, knowing what stage does what is purely academic.

2. By introducing this now we are introducing pseudo (and quite likely ill defined) structural model and moving away from behavioral formulation.

3. Without explicit rise and fall time information, it is easy to introduce inconsistent multistage models with switching discontinuity. To assure continuity the last stage in the rising transition should be first stage while falling and vice versa.
