It's from the first post by Yowster in https://steadyoptions.com/forums/forum/topic/6033-proposed-new-trade-type-for-higher-volatility-times/.
I can't comment too much the specificity of that here because this thread is public, but apparently they are still working on testing variations of the trade (see the new posts).
So the return matrix for that new trade is not 'up to date'.
