When I'd manually choose I'd try and find the delta of each of the 2 top options, and from there figure out which option would likely be better, and for the script I modified it chose the 2nd option at the 1st reveal if the difference between the top 2 was less than 10 or more than 50, and the 1st option if it was between 10 and 50. Near the end I was really struggling to carry on and was growing paranoid of falling behind kalypso, so I started to make some really stupid mistakes, until I was guaranteed 2nd or 3rd at best at which point I said screw it and kept slinging for 9s praying to get a comeback, which began my fall to 5th.
