The thing is I don't need a parser to tell me how I'm doing, I can see that just fine for myself. If a run isn't going well, I'll try harder. If in trying harder nothing changes then no amount of data is going to make me try any harder than I already am. All throwing numbers at me will do is point out where the real problem might actually be. We have the best potential to improve when it's on terms of our own choosing, because it will be us willingly pursuing improvement. Forcing people to 'get good' only makes things worse. Doesn't take a degree to realize that.
