Here I write about how to evaluate a system using Street Fighter 6 and NVIDIA Reflex Analyzer.
First, since NVIDIA Reflex Analyzer can only detect mouse click input, set the SA button to mouse click in the SF6 keyboard settings.
Next, open the training mode, set the stage to METRO CTY DOWNTOWN and your character to Modern Luke to begin.
Place the CPU on the left side and the detection box in the dark part of the stage.
Triggering Luke's SA2 with a mouse click spreads the effect across the screen so the detection box detects the screen update and displays the time taken.
Since it is SA2, you need to click while entering the backward movement. I used the gamepad and clicked the mouse while typing backward.

If you want to use it in other fighting games, you may find the blog post written by Zenji Nisikawa in Japanese useful.
