Canon Cinema EOS C70 shutter angle

[allves88]

Next week for the first time I am going to record files in Slow and Fast mode. 60 fps and 120 fps. I watched a video and it show that if I use shutter angle I don't need to change the shutter angle when I increase or decrease frame rates. In this video the guy says that I should only use the shutter in 180 angle for the 3 frame rates (23,98 fps, 60 fps, 120 fps. Is it right? I am use to do this way: 23,98 fps - 90º, 60 fps - 180º, 120 fps - 360º. What should I do?

Keep 180 drgee shutter angle, Change explouse using Aperture,ND and ISO
Shutter speed=1/(360 ÷ Shutter angle × Frame rate)
