LEED Dynamic Plaque vs EB Recertification

I'm not seeing much information in these LEEDuser forums on the LEED Dynamic Plaque (since 2014) as compared to recertification (since 2012). Is the Search function not pulling up the most recent entries first? I'm trying to advise a client and am searching for current information relative to the following: 1) LDP vs recertification (5-yr) -- pros and cons, time and cost commitment, others' experience with LEED Dynamic Plaque. 2) Coincidentally, is the percentage of recertifications for EBOM still hovering around 10%? 3) Details on the survey questions asked of building occupants -- is it really only two questions? One question on mode of transportation and one question on general comfort? What are the two questions? And how are these questions administered? 4) Is there any specific language or protocol for the method of VOC testing? Any updated and detailed information, re: LDP, will be greatly appreciated. Thank you.
