Ouch! That "4 percent" should be "0 percent". The "4 percent" is an artifact of the way I captured and posted the results.

Here's what happened. I first ran the Short-Term RoR for 9/6 JOB. I copied and pasted the "Distribution of Outcomes" table to a blank EXCEL file. Everything in the table is a number EXCEPT for the probability of losing everything. That cell has the variable "TripRoR". (if you have DRA-VP and click the probability of "lose 100%", you'll see "=TripRoR" in the Formula Bar near the top of the page). The 'lose 100%' cell value can change if TripRoR changes. Which is exactly what happened next.

When I next ran the Short-Term RoR for 9/6 DblDblBonus, the variable "TripRoR" in the 9/6 JOB table changed to the new 4% value that I got from the 9/6 DDB run. (you can see the 4% in the DDB table in my original post.) I didn't notice that the 9/6 JOB table had picked up the RoR value from the DDB table when I made the original post.

That also explains why the figs in my posted JOB table add to 103%. The actual rounded figs added to 99%, and that diff IS due to rounding.

Thanks for catching the error, Slowpoke!
