3 successes out of 15 total is a 20% success rate for >2 and <4. This could probably be taken a step further by comparing outcomes relative to draft position.
What is the success rate for >4 and < 6 and so forth, I wonder?
I think once you get >4, the data becomes kind of noisy, and you start getting into what is a "success" - for example, Patrick Williams, Cam Thomas, Isaac Okoro - do you consider these guys failures or successes?

I don't think there's a huge difference from 6-10 range but I will say that once you filter for BPM > 10 in freshman/sophomores, there are basically no busts and the vast majority are either stars or high impact role players.
