9 years ago Finally got a chance to find the timing, I think it is exactly 1 frame delay.
This is only a delay to the release of the block from an active state to allow it to fall or match again.
There is actually a slight additional delay when a block is unfrozen. This needs to be accounted for in the simulation to better approximate the real results in the game.
Research is needed, however, to identify the exact delay so we can be sure the fix is correct.
