I usually start the count at minus one
There's no reason to do this unless you can't keep track of the count well (in which case you shouldn't be at a table at all). Treat unseen cards as 0.

when the true count gets to plus 3 or higher I will double my betting unit.
You should probably be more aggressive than this. I'm not 100% sure you're playing with an advantage here, as +3 isn't super common. Remember, you need to bet enough at higher counts to offset the fact that you're playing at a disadvantage on lower counts.

I've been noticing at positive counts the dealer gets a winning hand of 20 or Blackjack more frequently than the players getting solid hands or blackjacks. I've also noticed I've been getting more winning streaks (3 or 4 wins in a row) on my minimum bets when the count is in the minus.
Here's where you need to be a little more precise in order to fully see what's happening.
The count being high, BY ITSELF, doesn't give you an advantage. The reason why you win more when the count is high is because you're hoping the count will come down - i.e. lots of tens and aces will come out. If the count is high and holds steady or goes up, then you SHOULD be losing those, because the high cards you were expecting haven't come out yet!
Likewise, if the count is neutral and takes a nosedive into negative territory, you should expect to win a lot of those - because a lot of tens and aces came out. Unfortunately, if the count is neutral you had a small bet out, so you won only a little.
That all being said, when the count is high, you're absolutely right that the dealer will get blackjack more often than when the count is low. That's GOOD for the player, since the player gets paid 3:2 on blackjacks. The actual win percentage doesn't change much with the count: at TC -5, you win 42%, lose 50%, and push 8%. At TC +5, you win 44%, lose 48%, and push 8%. The edge you get comes from the fact that you (a) bet more, and (b) are more likely to double and split, meaning that each of your wins will count more. You're still expected to lose more often than you win at very high counts.
