In the process of running scenarios for myself, I noticed that the result for 'Given a success rate, determine spending level for a set portfolio" for a 100% success was NOT the same result as when I manually adjusted the 'Spending' amount on the 'Start Here' tab to achieve a 100% success value. I thought you might want to know. Below is a random example demonstrating what I did. The only clue I have the two approaches MATCHED when I didn't have any Social Security earnings added, then DIDN'T match when I did add in Social Security earnings. I hope you find this helpful.
First, here is a random example where I kept changing the 'Spending' field until the 100% success value was teetering on the edge. Just $50 more and it goes below 100%. The spending is $87600.

Next, if I don't change any entry fields, but go to the 'Investigate Tab' and select the 'Spending Level' button and select 100%, the result should be the same (it worked when I didn't have Social Security income). However, it is not. It is in fact quite a bit different ($71,198 vs $87,600).
I would love to hear if I was just misunderstanding the calculator of if I indeed found a bug.
