Dear Doctor, I am lost without the metrostyle line. Help!

Oh I know – it bothers me too with those metronomically cut rolls. One minute you’re all alla marcia and the next without the thin red line in sight you’re all at sea! Take a fluorescent marking pen and write the true speed across the sheet large so you can’t fail to slow down in time. I have seen recently a roll where someone had written on it “Oi! Slow down mate!” just after the introduction. If you need this sort of reminder just go right ahead. You can but only gain by using these interpretational aide memoires!
