Increasing Spell Volume Capacity?

[singularityss]

A while back it was mentioned by SGAI that certain designated rabbi's spend literally all day (10+ hours) cursing gentile, and that this can be handled with training. With that being the case, would it not be possible to train oneself to be able to handle 3, 4, 5 workings at a time without burning out or spreading ones energies too thin? I assume they wouldn't be doing this if it wasn't effective, and 1.5-2 hours spent doing 4 or 5 workings seems much more manageable than 10 hours, unless there's something unique about what they are doing.

My guess would be that their curses are a form of "theurgy" and is more like partitioning and directing parts of their mega-thoughtforms - otherwise it seems extraordinary that someone could perform a "working(s)" in the traditional sense all day, every day.
