Eric,
Calacatta Gold is a great stone to work with. Some days even straight forward jobs can sandbag you.
When it happens to me or one of the guys it is usually due to human error or misjudgement of a process.
When you experience this you have to stop a second and rethink what you are doing.
Sometimes it happens because we scope a job wrong-think we can alter a process to save time.
We want to do the right thing for the customer so we look at a piece of stone which doesn't look bad and think we can just polish it up(cheaply)
Easy breezy but those are the jobs that suck you in sometimes. The customer didn't call you to refinish those areas because they are in perfect
shape. Charge full price for refinishing the surface and treat it as a system and have discipline when it comes to pricing.
This way your time is covered whether you can refinish it faster or not.   
John and Darek make a good point about starting with 220 grit diamonds.
I think that may be your key-220,400,800 then polish.
Calacatta will respond well to many polishing compounds.
Not sure how you used the 22 on this surface-it sounds under polished to me.
There are various techniques you can use when blending in polishes.
The short answer is more powder and less water. Increase the speed somewhat once the compound begins to dry out.
I can give you a much better explanation on the phone-feel free to call.
Mb-22 is an acidic polishing compound by the way.
It is used wet but like any polishing compound various techniques can be employed to increase its effects.

if your doing white marble you would be better off using mb12 if you have used it before and are skilled with
it. you can obtain as high a gloss as you need and you can also exceed the factory finish

i use mb 22 for terrazzo polishing and bottacino marble because mb22 is less acid and more for stone
that does not respond to acid because in the case of botticino it has more dolamite and less calcium carbonate

   Good evening partners. Repairing an etched white marble island today (attached). 800, 1500, 3000 then MB-22 polish. Not even close to the factory finish. And the area that overlapped onto the factory finish had dulled it.
 
   Kind of lost here. Just did a vanity last week using same method that turned out fantastic.
 
   Upon closer inspection, while the factory finish appears flat as glass, the polished area seems microscopically pitted. Not like an orange peel... much smaller. I don't know if this is the cause of the lack of clarity.
