As with the rest of the manips, you must hard reset and be holding up during buffering the intro. For an initial offset, by the math, you would subtract 134ms from your toto offset or use your union cave no encounter offset. However I have a theory you can't transfer over offsets like this and that the gym has different lag from the lab and union cave. After adjustments I arrived at subtract 154ms from toto or subtract 6ms from union cave no encounter for my offsets. My douglas offset is 10668.

There was a 6 frame window found at the same time as this 3 frame window, however it is broken and at least one of the middle frames does not work. Do not go for this, it is confirmed malfunctional.
