Good for visualization but it really needs the floor pattern; part of the "braindead strat" is that you move to the center of the rear exaflare, then to the intersecting lines on the floor (of the two south diamonds). This would make practicing much more 1:1 with the in-game movement.
The pattern can be found at https://github.com/kotarou3/ffxiv-arena-images/tree/master/dsu as "dsu-p5" if you wanted to potentially implement them.
