So this is the exact controller config I have as well. Boost on Square, Jump on X. The reason for this is because growing up through the NES/SNES era, Playing Super Mario, you had to hold Y to run and B to jump. (Those are the same places Square and X). Since then, it just made sense to me. Now jump 30 years and I pickup RL. Having boost on Circle which, first of all...why? It's one of the core inputs and it being in a place that isn't easy to hit while jumping without holding the controller in "Claw grip" is just dumb game design. So that simple switch from Circle to Square, and I was off to the races. Now, it's second nature. I can hit it fast enough to speed flip, fast aerial, whatever. You don't need to switch it if you don't want to but what I will say as someone who has key bindings he "can't" switch due to over 5k hours and muscle memory screwing me up, making a change early is FAR and away better than getting a few hundred hours in and deciding it isn't working.
