I wish there was an option to be able to turn off the chance to get a breakthrough. There is nothing worse than when you try to stop training at 95%-99% and you hit a breakthrough and the skill rolls over! 
There should be a checkbox to determine whether or not we want the RNG to roll to see if there is a breakthrough.
