Hope you found a clever way!

So what is the clever way?

So, instead of finding values for each path, you could start from the bottom, and just find which is bigger as you go up a row. You could do similar going down, but going up seems to be easier for bookkeeping.

What if there is another way? What if you take the mean of each row, and then figure out values as a + or - for that row. That's the method that keeps popping up in my head, but I haven't had the minutes to sit down and try it...because I'm busy reading my Starfinder rulebook...
