Aloha dickens,
You have Chunyi saying not to mix them like that, and will be getting together with him on the 25th for the Level IV intensive. Hmmm...to me it sounds like a wonderful opportunity to ask the question. 
A lot about Level IV is from the questions you ask.
Much Love and say hello to my wife Darcie at the class, I think I may be at the zoo with Mr. Handsome.
