I can live with your statement about differences, but the devices like Sarin/Ogi are full of machine error, averaging, rounding, etc. Nothing is more accurate than a direct measure. A calculation based on corrupted data is pretty much a corrupted final product.
I agree. But we have to establish an acceptable standard of error with regard to measuring. I find it interesting that machine owners talk about error in their measuring but when they use their measurements they make averaging measurements a "norm" which gives a more false analysis than the "corrupted" data. Also, they use incorrect measurements or measurements that have no meaning to the cutter.
My scoring anaylysis(for the time being) uses the Sarin data and I''ve found that only about 50% of trade eyes can detect a 6% deviation in final scores.
It can be made to accept any measuring machine''s data, so in effect the BrayScore platform can be used as some sort of replication/accuracy tool to judge various measuring devices for accuracy and replication.
However, like clarity grading is acceptable by 10X, I think cut measurements are at an acceptable standard where they''re at now, IMHO. Just because technology allows us to measure more accurately, doesn''t mean that it''s necessary or is beneficial to do it.
I''ve heard of machines being able to measure the polish on facets in "nano angstroms" or something like that. Totally ludicrous. Can it be done? Sure. Will it help us sell more diamonds? I highly doubt it.
