I can allocate about 20 hours of supercomp time to this task before I need it for something else. So we'll see what we can learn from RO.
To those playing 20/18x. Ur in a backgame most often so play it at least somewhat like one. Hitting and breaking the 20 pt anchor is a huge error as the counter attack, if it succeeds is very strong and if it doesn't little is gained.
