I agree the name is suboptimal, but maybe we should rather try to describe what it is for: Namely re-drawing for a multi-equation system. Perhaps something like 'syscoeffdraw'? That would also leave the door open for other underlying distributions in the future. (Would that be a likely or sensible generalization?)

(Please expect that editing the produced plots is likely going to fail. Jack had commented that it might still be useful.)
