Simplified Tornadic Objective Rating Measure
after a few years of work, i think ive made one of the best windspeed-based tornadic rating scale. it used to be much more complicated, taking into account latitude, ambient pressure, recorded tornadic and non-tornadic winds, measured wind curve across the vortex, and much more. however, i realized that was an absurd amount of data, i simplified it, giving it the name STORM (Simplified Tornado Objective Rating Measure)
its still quite a bit more complicated than the EF scale, so it probably won't get used by many people, if anyone uses it. but ill still provide the link to the desmos graph
v is either the peak measured velocity, or max DOW measure, whichever is available, with probe speed superseding DOW measurements

EDIT: Comparison to the EF scale added to graph
