If it were bud, it would require about 20 grams of flowers to produce 4 grams of oil. We would typically use one 300 ml can for a 20 gram tube.

The violent boiling was probably dissolved gasses coming out of the alcohol, as it mostly boils quietly with occasional bumps. It is boiling away, you just don't see it exiting.
I control the vacuum pressure of the system until we get past that stage, so as to not make a mess in the chamber, and only go to full vacuum pressure after things calm down.

We heat the Everclear to 115F, but that isn't necessary until most of the alcohol is gone.
How much surface area do you have in your pool, versus depth, and how are you keeping track of vacuum pressure?
Here is a boiling point chart for ethanol at different pressures, and you will note that at 1.3" of mercury, ethanol boils at about 53F.

it was in a bowl. surface area was maybe 4x4 inches, and 2 inches deep. it boiled great right off the bat for a few minutes. then it all stopped. I even changed pump oil out for fresh stuff. still nothing.
came back the next day... re did it.. and it boiled like crazy!!! so I stopped it instantly and wanted to show my girlfriend. tried everything again to get it to boil like nuts and it wouldnt do it, I looked like an idiot in front of her!!
maybe the everclear somehow got cold because I was purging near a door so the exhaust fumes could vent outside?
I am keeping track of pressure via a gauge in my vac it pro chamber..
I can hit 27.5" of mercury in a 3 gal chamber with a 5 cfm stage 1 pump at 2200'

2" is a pretty deep pool for a 4" surface area and I would expect it to take awhile. Can you use a larger container, so as to have more surface area and a shallower pool?
27.5" isn't as low as I would expect from a 5 cfm pump, unless you have either a leak or something outgassing (boiling) inside the chamber. Have you checked for leaks.
The last two inches of vacuum make a big difference in how fast things boil.
Are those stress cracks that I see in the lid, behind the gauge, or an optical "dellusion?"

do I even need to use butane? that shits getting expensive at 6$ a can. is there any way I can just skip that step and rinse with everclear right off the bat?
or find some methanol?
yes those are stress cracks in the surface of the lid. another use here has the same chamber with no cracking. dont think there is any leaks, but ya never know.
I dont think I can achieve a full vacuum due to my elevation, 2000 feet.

I know it's possible to perform extractions with just ethanol. Not sure the best way or how long to soak. Might find good info at skunkpharm site.
Full vac is full vac...whatever elevation you live at.

Here is another graph http://www.nypts.com/Downloads/Altitude.pdf which also shows PSIA and Hg. You are correct, at 2000 feet, your -27.5" Hg, is equivalent to 29.~"Hg.
Have you tried to use a shallower pool yet.
I would replace that lid before it lets go and wrecks your extraction, if not your day. High cyclic fatigue is occuring from constant oil canning, so I would go to at least a 1" piece of Lexan to reduce flexure.
