I don’t think gradually improving your sens is going to help the process. After all it’s just musclememory.
The best way is to just set time off to practice yourself and your new higher sens. Might take days or weeks of DM and perhaps casual MM to get used to a higher sens depending on the gap between new and old settings.
you only really need to turn 180, but you need to be able to do so in one swipe, and not in 1.5 swipes.
So we do the math, your new sens will be 0.7 * 3/2 = 1.05
np happy entrying
also dont gradually increase your sens, it will only make your spray shit for longer
