I'd probably have Vegeta and Goku making large increases compared to their Boo Arc selves, since Vegeta believing he could distract Beerus should account for something (though he did know SS3 Goku got two-shotted, so it could go either way with that).
Regardless, pegging Vegeta at a far higher level than his Boo self does reduce the ridiculousness of his rage boost even by a small amount. I guess I'd be generous and say he surpassed Pure Evil Boo, maybe Pure Boo too.
