Secondly, I remember from my time as a grue that there was another, slightly more complex method of scaling? Something involving a full-scale picture of the desired model, then taking its height and the height of the piece you want to pep in order to get a ratio, then multiplying that by your own height to get the pep piece the right size for you (I've said it in a really long-winded way, but talking isn't my forte (don't judge, it's not John-117's either
)).
