As requested, the results of the survey I conducted on MapleTrader and MapleChatter earlier this year have been posted to https://www.uvm.edu/~pmrc/ Look at the right under "Recent Publications".
There are two parts:
1. Survey including all respondents.
2. Survey including only respondents who used 10% or more CV in their maple operation. This allowed me to only examine those people who actually tried enough CV adapters that they might see results.
In addition, the presentations I gave at some of the equipment manufacturers are also posted there (PMRC Research Update 2010 & Sap and Vacuum Dynamics).
