its great having a video that summarises some of the basics that tend to get asked here alot , so far a few points of concern for me would be
1000hz vs 500hz doesnt matter and some hardware as well as some games perform better / more consitent on 500 than on 1000
another nag i've got for you besides that is that pseudo science about 1600 dpi being "superior", now dont get me wrong from a certain standpoint( accel) it has its benefits but this summs it up quite well ( in regards to those latency meassurements between 400 and 1600 dpi some pupular yters have been spreading)
----
a change in hipfire fov wills still affect our perception of "sensetivity" (unless you strictly seperate distance and sens) this isnt the whole truth, the whole fov/ aspect ratio (+stretched res bs ) thing is another rabit hole of itself so i get why youd only briefly mention it or leave it out.
criticism aside
the whole video and effort you put in is commendable and id consider using the link in some cases in which i am too lazy to explain stuff i like it alot, and appreciate the video quality the whole sens thing is something many hardly understand because there is a lot of heresay going on so getting it in such a compressed formfactor is nice
