hs-Tnl verification- precision criteria

Hello, 
We're working on our verification of the hs-Tnl iSTAT cartridges. I am looking for assistance on acceptable criteria for precision for this analyte. After reviewing the IFU and method evaluation from Abbott, I cannot find criteria with supporting evidence. The precision in the IFU is not to be used for precision criteria per the method evaluation. The method evaluation states that precision must include SD and %CV but doesn't provide guidance. 
Does anyone who has verified this test have any documentation to support the acceptable criteria used to accept this test?

To meet the 4th universal definition of "high sensitivity" cardiac troponin assay, I would utilize <=10% CV at the 99th percentile upper reference limit. This limit could also be applied for i-STAT hs-TnI Controls Levels 1-3.

Best,
