Just to make a few banal remarks on the number of iterations:
Users would be able to compare #iterations on different data with the same program if that mattered to them.
Any comparisons with any results published elsewhere by what is supposedly the same algorithm should however be highly circumspect.
Results will depend a little on how the algorithm is initiated and a lot on the criteria for convergence.
Rosenblueth and Wiener pointed out that the best model of a cat is another cat -- no, preferably the same cat. In the same way, only -survwgt- can be compared with itself.
This is not, directly or obliquely, a criticism of -survwgt-, which I have every reason to believe to be an excellent program.

As the author of the program in question, I've added an option to show
the number of iterations completed (although I'm not really sure why one
might care), along with an option to control the maximum number of
iterations the program will go through before giving up.
I'll make an announcement on-list once the new versions are up on SSC.
