Strobing has to wait for the refresh to complete, so the middle of the screen would be delayed by about 4 ms at 120 Hz.

I believe it's 8.3ms + 4 ms.
120hz Lightboost is identical to 120hz Benq Blur Reduction with a vertical Total tweak of 1497-1502, with a Strobe Phase of 000 and Strobe Duty of 009. But Strobe phase 000 has up to 1 frame higher input lag than strobe phase 100 (without a VT Tweak) or Strobe Phase 041 (with a VT tweak), so it's probably 1 frame + 4ms. Many people complained about feeling input lag with Lightboost and with benq BR, but with a high strobe phase, it's gone

TL;DR: The strobe seems to begin at the END of the current frame, rather than at the start of the current frame. This is done to minimize crosstalk at the bottom of the screen, since there must be a delay (as you said). I'll explain more about that later if anyone cares.
