Success rate percentage oddness
Similar question to: https://www.reddit.com/r/adviice/comments/1pfsy3g/inconsistent_success_rates/
I've been noticing some oddness myself with success rates, and similar to that linked post, I put it down to user error on my part.
However, I've got a situation where I was 100% sure of the changes I made, then rolled back, and success rate did not return to where it was before. I then verified this behavior across multiple of my saved scenarios:
Scenario with survivor age of both my spouse and I at 100. Verify "Projections" page shows "Up To Date". Click it anyway, just to be sure. Refresh page, etc. Verify success rate (in my case, 99%).
Go into "Advanced Options", change my Life Expectancy to 70. Save, and Recalculate. Success rate drops to some new amount (77% in my case).
Go back into "Advanced Options", change my Life Expectancy back to 100. Save, and Recalculate. Success rate does not return to original amount. In my case, it went up to 93%, not back to the original 99%.
I've done this now on several scenarios, just to verify this happens. Change a single item (life expectancy in "Advanced options"), recalculate, change it back to original number, recalculate, and I don't end up back at my original "success rate".
Can changing the Life Expectancy in Advanced Options change some other settings that then don't get set back when putting the life expectancy back to it's original value? Or is this a bug?
And just to re-iterate, I've verified on several unlocked scenarios that just changing one value, life expectancy, recalculating, then changing it back to it's original value, and recalculating again, does not return me to my original success rate. I'm always 3% to 6% lower.
Any help appreciated.
