I see the Europeans have a shift pattern.......where you push DOWN on the shifter for the next higher gear.........
But in the U.S of A........we have to lift up for higher gears.........I am torn......
I could see the "downshifting" into higher gears (which is upshifting here) if you wish to bang through the gears fast.......
But then to downshift, you need to lift up on the shift lever. I don't know.....seems like a "Horse apiece" to me?
I cannot decide!! Lol! What do YOU say???
This is all for fun of course!!!

This is a margin call of sorts.
If you got the heel/toe shifter set up it is a moot point.
If you don't then I would think that you would be better served with the pattern of pushing down for downshifting simply because it is related to braking issues which are more critical than speed issues.
You can apply more force, and be more authoritative in using the shifter going down than going up.
If you gotta stop and stop RIGHT NOW, that comes in handy.
