So here's the thing,  this tek is not a "maximum" yielding tek like cybs. I found the average yield to be around 1%-1.5%. But keep in mind, this is likely due to the dry tek style, and no heat during pulls. 
You can use the microwave technique on a wet tek. It works. 
Another thing,  Ca (OH)2 has a lower pka than NaOH, so the lime might not as effectively free base all the dmt as efficiently as lye.
Just some things to keep in mind
It's not a bad tek, and it's not the "best" tek. It meets my needs,  so I use it.  

Sometimes it's good for a change. Other times it isn't.
