I've reread my message my intoductory sentence could be misleading. Let me
try again:
"Thanks for all the help. I've run the numbers through Excel and believe
the following calculations are correct. Except for the first few, I have
rounded the numbers to one decimal place."
[numbers follow]
By the way, to answer my initial question, the 50mm f1.2 is between 1/3 and
1/2 stop faster than the 50mm f1.4.
