Darin, you test more than enough to be doing the Tight Regulation protocol!
Why don't you come over to the TR forum and start posting there? The TR forum is much busier and even if you choose to do the "Relaxed" protocol, we have lots of others doing that who still post there.
You'll get more eyes on Charlie's numbers there too!
Good call on going up to 2 units! Matter of fact, you may be holding the dose too long. After 3 days (6 cycles), if you're not getting better nadir's, it's time to go up again. Depending on how far each dose takes him will make some difference on if you'd increase .25 or .5 each time too
With him dropping that much at +2, you should plan on getting a +4 or so too tonight. If that +2 is lower than the Pre-shot, that can mean they're going to have a very active cycle.
