Findings from Noodalls - Tekken 7 has less input lag on XB1 than PS4

Well this is a little awkward isn't it? Noodalls tested out the input lag on the Xbox One versions of Tekken 7 and as it turns out, it in fact has less overall input lag than the PlayStation 4 Pro version. In the previous findings, Tekken 7 on the PS4 measured at 120.1 ms (7.2 frames) with the PS4 Pro matching that. On the Xbox One version of Tekken 7 however, the game was measured to have 104.2ms (6.2 frames) so that is a 1 frame difference between the two consoles. This marks an unusual precedent since historically Tekken games have always been played on the PlayStation versions competitively. Do tournaments now use the XB1 version? Or is everyone content on playing on the PS4? Once again, big thanks goes to Noodalls for the findings, added below is the YouTube video he recently put up testing the two versions.

After finding a significant difference between PS4 and X1 with my unique input lag testing method, I wanted to perform a more simple test to ensure that the results were consistent.
Input lag compared between the two systems. X1 in on the left, PS4Pro is on the right.
Monitors are BenQ Zowie RL2755 on left with standard Xbox1 connected, ASUS Evo monitor on right with PS4 Pro connected. Inputs are generated by arduino connected to two Brook UFBs updated to v1.9 (latest at time of test). Wire length and USB cords same length. Code should result in 4-8ns difference in timing between when signals are sent out. There is also a red LED there that lights up when signals are sent out, but this is rather hard to see.
You can watch youtube videos in HD and pause, then use , and . to advance and rewind one frame at a time.
This video is consistent with my earlier findings.
