Once your entry system is in place, there are two competing ways to boost RR. Target manipulation vs size manipulation. Set a desired RR and then adjust the target/size balance all the way to one side, then all the way to the other. Test every possible combination with each fixed RR of choice. The options are finite, in case your pathetic laziness tries to convice you that the task is unrealistic. I've done the cost benefit scans. It is a highly fruitful and extremely lucrative project. You're welcome.
