Knight,
>>>A total of 11 blank samples were submitted blindly to Ledoux & Company, which are randomly introduced throughout RC holes 1 through 5, averaging 0.008 oz/t.<<<
The way I read this is, these are "calibration samples" submitted to Ledoux without them knowing which samples are real and which are the blanks. Then when the results are reported Naxos knows which sample should be reported as .008 opt. If Ledoux's number disagrees then an offset value can be generated for the remaining samples. This may explain why some of the 10 foot intersections are missing from the latest table. If these were the depth's that had the blanks substituted for them , then they wouldn't be reported.
I'm in the semiconductor testing business and due to problems with accuracy and resolution from tester to tester it is common to generate a "golden unit" of precisely known value. This unit is then tested, its new value stored and an offset is generated based on the known value versus the new value. All other devices are then tested using this offset to determine if they meet specification.
Same thing here, if Ledoux reported the blanks as .006 then the actual samples would be reported .002 too low. Conversely if the blanks reported say .018(just for grins) then the actual samples would be reported .01 too high. It would be interesting to know what Ledoux did actually get for the blanks.
Henry, PERFECT GAME wow, go New York, did I once say I was a traitor from LI, never mind.
