Okay Mark, nothing in your post addresses the question "Does SCHRS require an ISAF certified measurer?"

Are you saying the Organizing Authority of a particular regatta determines if a measurer needs to be ISAF certified? Or the OA of a particular region has the authority to enforce the measurement criteria? This sounds a LOT like PHRF and no matter what you say PHRF if the WORST of all of them and it's NOT a regional phenomenon. The sh!t fights that happen with PHRF make us and DPN look like we are making hot monkey love.

So, for me I need a clear set a rules that are enforced consistently across the board globally or at the very minimum nationally. Everyone plays by the same set of rules regardless what OA we fall under.

What is the definition of un-certified data?
