My scope has 30, 35, 40, 45, and 50, so I can’t just divide by 2.  But if I understand correctly, once I have developed my 16x dope card experimentally, I can make a 40x dope card by multiplying each holdover by 16/40.  Is that correct?  Would it be more accurate to make a 40x dope card experimentally, and derive the 16x dope card from that?
