Shifting with the wheel buttons

I am new to this stuff. I have a Wingman wheel and the two pedals for
brake and gas. The wheel has four buttons on the wheel. I have set
up the controls so that I up shift with the right top button and down
shift with the right bottom button. I have set the left bottom button
to be the clutch. I've been using it that way but it occurs to me
that it might be more natural to have the up shift on the right bottom
button and the down shift on the right top button.

I'm curious how others that use the wheel buttons for shifting do
this.
