Hey Gavin. Great question and thanks for asking. Yes! You can manually enter club distances. This is important to club recommendations, especially if you are a new user of Golf Pad and your actual data is still being collected. After about the 10th round, the app will be able to give you personalized recommendations based on your real distances.
The enter average distance manually, go to settings > club recommendations > enter typical club lengths.
Let us know if you have additional questions.
