Thanks for following up! I had another play and I see what you mean about par, makes sense. It would be great if the 4r perhaps isn't introduced until the game

Thanks for following up! I had another play and I see what you mean about par, makes sense. It would be great if the 4r perhaps isn't introduced until the game gets into the later stages of editing buffers – I think that would avoid repetitively introducing the same ideas before they can really be used. Nice work though and nice idea.
