Dr Lara Boyd says brain changes peak at 50–60% practice success

"And so we see that when we make that game hard, when they're struggling, when they're success rate is right around 50 60%. So it's hard. This is when we're seeing the most neuroplastic change and specifically we're seeing them change their brain structure most at that particular time as they're practicing the task."

Dr Lara Boyd describes a computer-based training task used with stroke patients and says her team adjusts the difficulty while mapping participants’ brains. She says they see the strongest markers of neuroplastic change when the task is hard enough that success rates sit around 50–60%, rather than being too easy or so hard people stop practising.
