For average EV, I think you are looking for “$EV diff” stat, have your player ID set and it will show the hero stat.
For Cbet success stat, you may have to use the create stat feature for this because we don’t have one pre-set for this yet. If you need help with the formula, please send us a message though support page or headset/support icon in DH2.
