After lengthy discussions and recalculating, I came up with this chart, using the 'Small Numbers Rankings' Akira Toriyama gave for SSJ God Goku, Whis, and Beerus, to do a bit of a more 'accurate' power chart.
This chart, I think better than any I did before, demonstrates the overwhelming strength of Beerus and Whis in comparison to GT powerhouses.
In my estimation, I believe GT Gogeta could fight on relatively equal grounds with Beerus, but get stomped by Whis. Even in DBNA, Son Goku and Vegeta's powers (less than 1) are nowhere near Beerus and Whis, and even the mighty Rigor only ranks a 2 in his base form in comparison to Beerus' 10. It also demonstrates how much of a buffer the SSJ5 transformation grants Rigor in his prime, showing why this is the 2nd most powerful form next to SSJ God.
For the record, though he is not listed, I only rank Omega Shenron a 3
