That understanding is wrong. A full measure rest has a duration like normal rests, thus you will have to scale it according to your time signature. There are many ways to achieve that. My personal favourite is using R1*<time signature>, e.g. R1*4/2 in your case. To cover 4 bars you would write R1*4/2*4 HTH, Michael
