|Clarification on .5 log
Mar 25, 2006
You answered me on March 18th with this, "If you went from 100,000 to 32,000 that would be a 0.5 log reduction (5 - 4.5 log) and so on". I am unable to tie mathematically back to 32,000 with 4.5 log. This seems to be an example number and not a number one can actually calculate from 5 log to 4.5 log. Is one supposed to guesstimate based on the median between the abosolute copies while comparing back to the absolute log number whether you are within a .5 log or not of the range? e.g. 100,000....32,000..10,000 = passes the .5 threshold. Can one also deduce that there is .2 log or .4 log or the smallest fraction is .5?

You can't do this in your head. It is a direct mathematical relationship that can be done with most pocket calculators. For instance, log (100,000) = 5, or log (32,000) = 4.5. You just punch the number in and hit log and the logrithmic number is provided.
