We can remove this "Up to" column to make the table smaller if "BV" and "WT" are still valid in 4.31+ (all the others are valid)
This "UP to" can already be necessary for CB life with playstation, i read something related about this being not anymore available on ofw (but if you still have it installed it will continue to work) since the project ll close.
