Can anyone help me find the study that gives us a new accuracy percentage for the HGN under a 0.08 law? A link would be helpful...

http://www.mass.gov/mdaa/mvcrimes/Florida%20validation%20study.pdf ("The limit now has been lowered in a number of states to 0.08% for the general driving population. �Zero tolerance� is in effect in some jurisdictions for drivers under age 21, and commercial drivers risk losing their licenses at a BAC of 0.04.% It is likely that additional states will enact stricter statutory limits for driving. In light of these changes, a re-examination of the battery was undertaken by McKnight et al. (1995). They reported that the test battery is valid for detection of low BACs and that no other measures or observations offer greater validity for BACs of 0.08% and higher." . . . A recently-reported NHTSA-funded study was conducted by Anacapa Sciences, Inc. in collaboration with the San Diego Police Department to examine the validity of the SFSTs for both 0.08% and 0.04% (Stuster and Burns, 1997). Officers� estimates of whether a driver�s BAC was above or below 0.08% or 0.04% were found to be more than 90% correct.

This may be it:

The last link on the page is the "San Diego" study which gives the alleged accuracy rate of 88%.
