ShortestPathFinder- help to understand the optimizations

Question

Hi, could somebody please help me to understand the optimization parameters in the ShortestPathFinder? Here are my questions:

Why does it take longer to calculate with a lower number of "Number of Iterations" (Options: When any condition passes, Number of Verifications: 1, all other empty) In my workflow (reorder 200 points) with a value of "100"iterations it runs forever, with "1000000" runs less than a 1 minute)
What is the purpose of the "Iteration Rounds" option? Is there a link to the "Number of Iterations"?

Thanks

I have read the use case from @Mark Stoakes https://www.safe.com/blog/2016/11/fmeevangelist158/ but I don't get it.

Here are some screenshots (FME Build 21302 - WIN64) and the settings to make it clearer.

Routing5 To question 1

Setting 1: 10000000 Iterations needs ~6 min

Routing1

Setting 2: 10000 Iterations, I cancel it ~30 min by myself

Routing2 Why is it faster/ work with more iterations?

To question 2

Are these settings equal?

Routing3 =

Routing4
