Yeah, it's more theoretical than practical at the current stage in his series, though I'm sure once he's finished he'll hand us a complete and detailed "how to make monsters" guide, possibly well before WotC publishes such a thing.Not too closely. I know he has been doing excellent work, but most of what I needed so for I had already converted and used. I am good through chapter 2 of the AP. I will reevaluate conversion methods after I have had a chance to absorb the monster update this weekend.
I'm really interested to see how he reverse-engineers the monsters. I'm decent with numbers, but this guy is crunching data at a level well above what I'm familiar with. Looks like he must put a hell of a lot of work into it, too. All in all, I find it pretty fascinating and useful!
