A whole lot more of the briar will end up as dust.
That's really about it. It's tough to talk about, but easy to demonstrate, if you know what I mean. Keep the gun moving, and depending on your orifice size you're going to want to hold the pipe further away. If you've ever blasted glass, you know that if you hold the gun in one spot for too long, the piece you're working on will shatter. On pipes, you'll just dig through to the other side in a real hurry. When you're first starting, use scrap pieces of briar to get used to the way it works - you don't want to ruin a perfectly serviceable pipe. And the wood will give a different blast depending on how you hold the gun - perpendicular, with, or against the grain.
Other than that, it's mostly experimentation.

I think it depends on your media, your pressure, and your expectations. It takes me about an 45 minutes to an hour to blast a pipe evenly, but I'm not trying to get crazy depth and my rig runs around 95 PSI which is well short of a good setup.

An hour? That's way too much time. What are you using, fairy dust?
If you're running @ 95 psi, try a smaller nozzle.

Nah Kurt sold me a big bag of rice but he said it was the best thing to use but it means I have to have a big nozzle on.

Although he has been absent from this forum for a while and I hate to disagree with you but, we all know that Thad Johnston is the biggest orifice around
