There's a streamer who got radiant on all servers and uses a sens very similar to yours. His nickname is FRTTT, he uses 0.755 sens and 1600 DPI. He recently posted a video on YouTube showing how to control the aim with high sens. It's in Portuguese, but you can use YouTube's automatic translation.
This is the video: https://youtu.be/Epq1V-L1WmA
