ok, i follow your maths. but are you sure the difference is zero? as you said before:
"it wont even make a 1ms difference to your page if you have a cfif instead of an IIF." so is it 0.5ms, 0.0ms, 0.99ms? i assume you've ran some metrics on this. "Never use IIF - If you can help it, don't use the IIF function. It is half as fast as a normal CFIF. " http://www.fusionauthority.com/Article.cfm?ArticleID=2511 "The "immediate if" function (IIF) will process nearly two times slower than a cfif/cfelse block that accomplishes the same thing" http://www.phptr.com/isapi/product_id~%7B0661582F-55B1-40C7-8B29-61D2E438E89A%7D/articles/index.asp etc. so either there is an infinitesimal difference, or it takes twice as long.

The total combined may add a few ms extra as all the fractions of a ms add up, but that's like counting grains of sand.
