Price check on orbs

Is there a comprehensive guide that breaks down the values of the orbs in onslaught out there? I.E. how many orbs of fusing = 1 chaos. or augmenation = 1 chaos. ect

There probably is not. However, from paying attention to trade chat here is what I've learned.

1 exalt is somewhere between 20-23 chaos
1 chaos is equal to 2 alchemy or equivalent.
1 blessed is 1.5 chaos
1 divine is 5-6 chaos
1 gcp is 2-3 (usually 2) chaos
1 regret is 1 chaos (sometimes 3:2, depends on person)

The equivalents for alchemy are fusing and to a lesser extent scouring

As far as chromatics go 17-20 are about a chaos
And I think about the same for alts
