What's the difference between "Jedi's Trick - Horizontal" and "Jedi's Trick - Vertical" and which one is more useful for conversion (if any). Would the difference be using MDH instead of MDV to calculate the sensitivity as seen in this topic?

 

same question here

I couldn't explain you the diff because it's way too advanced for me but on the original thrend somewhere the author actually said it was 'better' to use the vertical version.
