If you don't want to do left-right-left because you're too tired (with the stick
or with the d-pad), then just do a circle, if the circle first goes through
"down" your ship will pitch up a bit, otherwise will pitch down
(sometimes it's useful to BR while pitching down).

Yesterday, I was doing several BRs this way without even noticing.

I noticed many people complaining about them, so I thought I would share...

Also: often when I failed a BR, I thought the game was broken but in fact it's
because I was only doing left-right (missing a command), so to avoid this it's
best to try a left-right-left-right, it has more chance to succeed.

Oh yeah last thing, when doing BRs with the sticks, you don't need to push it
completely left or right, just a bit is enough, I think I miss 1 BR out of 100
that way (not taking the near-impossible ones into account).

Hope it helps!
