I've made this little windows app that helps you decide on which row/column to choose in Mini Cactpot. I'm not a programmer, so the app is really crude (and ugly!), but it works :) Code is a mess too and far from being optimal.
#HOW TO: "0" = unscratched value. Change any 0 (zeros) to values that show up on Cactpot and hit "Calculate". In blue fields it will show all the expected (probability term) values for all rows/columns. You may get less or more, but in the long run the expected value is what you would get if you'd pick that option hundreds of times.
TLDR: Input cactpot values in place of zeros. Check the blue fields and pick the row/column with a highest number.
