You can create a coefficient of angular momentum with the rate of incident. So something like (v•Hz)+X•Y² so long as your keep or above 1.5 you are good for most cases. When you really want to put in work getting up to about 2.3 is well tolerated. Any more and you are gonna lose your displacement over time. The main use for X¹ or shaft is ensure compliance with the minimum approach angle.
