Hey cap, I don't think anyone here wants come across as belligerent to you. You seem like a nice guy, and you don't seem to be a charlatan (see cipherblackjack thread for examples).
I think the reason that you've been interrogated so much is because, quite simply, you've got the collective body of the message board confused.
You must understand, the knee-jerk reaction of this crowd, when confronted with a "system" with no particular degree of proof, will dismiss it as voodoo. (zg's query about knowing basic strategy is a fairly automatic part of the vetting process).
If you do have a verifiable, repeatable, system, then we'd like to figure out what the heck it is. It may match to some commonly accepted advantage technique, or it may be something totally new (which we would all love to copy!).
You've been playing quite a while, and you're up quite a lot. The law of large numbers would imply that you've got something going. Note that an exception to this would be if you played relatively few bets with very large amounts. Care to share more information re: your betting, and how much time you bet various amounts in your bet range, and how much you bet in a "high count" vs a "low count"?
I'll be frank, I'm increasingly pessimistic of the odds of the dealer peek being a useful play, because of three constraints:
1) The dealer has to be checking for BJ (not all hands)
2) The dealer has to check the wrong way (very rare in my experience)
3) Any information from a tell is gleaned after you already make your bet, limiting the most obvious profit-increasing opportunity.
But... you mention something with the dealer cut, what have you got cooking there? If the dealer saw a card, I would only imagine they would know if a single card was cut into or out of play, or maybe what the very last card of the shoe would be (but they wouldn't necessesarily know when the end would arrive).
There are some player techniques with the cut, mainly involving spotting the card, marking its position exactly in the deck, and then "steering" the card to the desired location during play. But that doesn't sound like anything you've mentioned, and it would probably be near impossible at a table populated with strangers.
PS - The worst strategy listed on Wizard of Odd's page is literally assuming a ten is in the hold, which has about a 10% edge. A mimic the dealer strategy had about a 5.5% edge. So, even a horrible strategy like mimic the dealer is still better than slots or keno!
