If you are going to skew your walls so they are not parallel, is there a minimum difference in angle you should achieve?
Minimum wall angle?

If you are splaying (a common word for angling the walls in studios) for stoping flutter echo, about 6 degrees is the minimum.
If you are doing it to direct early reflections, then you have to do ray tracing etc.
