Is there a point to all this? What are the advantages disadvantages?
That's half what most people would use.
The disadvantage is that if there isn't another water you won't get a good separation layer, if one at all.
I remember seeing someone's first extraction attempt and they mistakingly put only 500ml in a 100g mhrb extraction and the non-polar layer never formed. Took him a while to realize he'd only put 500ml in and not 1 liter.
As with your base, it's better to add excess water than too little.
But all this information, and more, exists in the thread I linked and others.
