Thanks for your feedback, Rizla. This particular training calculator does tell you which specific drills to use in order to maximise the training efficiency.
As for the rest of your requests, they're individual. For example, different players will require different amount of greens in order to gain a star. Also, the gaining of a star depends on the average skills of used drill. I thought about making such a calculator, but there are to many individual parameters going into such a calculator. The best one could do is a calculator based on the minimum requirements for a fast trainer. I'll give it a thought, though.
