I noted that the online documentation for Delay Information gives the following examples:

The examples SS1 and SS2 are wrong imo: The delay time should step up at time = 40 and thus the delayed input should be held starting at that point in time until more recent information becomes available at time = 40 + 30 = 70 for SS1. Conversely, for SS2, the jump should be at time = 40. Is the documentation up-to-date?
Unfortunately, I am only using Vensim DSS 6.3 occasionally, so I cannot check the most recent release of Vensim. (Vensim DSS 6.3 will exactly reproduce the examples cited above, though, and thus does have a bug imo)
Best regards,
