Yes, I realize now I haven't approached that one the right way.

I wanted to compare the difference in I across a few different versions of the same circuit (the Lin to Exp converter). 

Different people use different R values for the voltage divider coming out of the CV summing mixer and  going into the Base of Q1 (and others don't use a voltage divider at all...) - I just wanted to get an idea of what different currents different people were using - and I *think* I can now work that out at least well enough to make a comparison.

Thanks.
