Assumptions:
- X Acc in slot 2, X Speed/Special in slot 4 and Poke Flute in slot 14. No other items are used.
- X Acc and X Speed/Special are reached from the top of the inventory, and Poke Flute is reached from slot 4.
- All move uses require no directional inputs (assume all are in slot 1).

NOTE: These timings were done with human inputs (i.e., not frame perfect) and manual timing, so they are not 100% accurate.
