The theory that Pittman recounted wasn't complicated. Regarding the connection of theurgy circles and magic circles, in Gawain's understanding, it was actually just a process of "frequency conversion compatibility".
Although the structures of the two differed, and the rune system and effectual mechanism were also different, theurgy circles and magic circles were essentially a kind of system that consumed magical power and produced effects (energy accumulation magic circles like the Magic Web actually did not produce magical power either. It only concentrated and compacted the dispersed magical power already existing in nature. There was also the loss of its own waste energy in this process). Such systems had the innate possibility of being connected: so long as a suitable transfer pathway was found.
