The guidelines are reviewed and revised every 4 years at minimum.  Usually the state committee only reviews them the absolute minimum amount though.  The next review won't start until May 2018 which will drive the changes to the 2020 guidelines.


I think plenty of people are in agreement the guidelines need changed, but getting folks to engage the committee and stand their ground is something only few people have attempted.  If the committee admits the guidelines need changed, they are admitting what they've been doing isn't correct or isn't working.  They believe the guidelines are near perfect.
