As I said it depends on both native aspect ratio and custom aspect ratio, as well as the FOV of the game. The % is not the same for FOV 90 and 91 for instance. So it's not really possible to make a list for it.
You have to find the relation between what the horizontal FOV should have been without stretching and what it is with stretching, then do the monitor distance math of the difference between them.
In this case you should use vertical scale 142%. A function to do this automatically is in the works.
