The lowest reported values from the DaTARIUS unit for the LG was at 4x, however, if you look at the table relating to the TRT results, only 16x & 18x are rated as good. Nowhere can I see in the article stating that 4x writing for MCC004 on LG was considered the best so I don’t really understand your complaint
A truely comprehensive review across every major media/drive combination available in the market today would be perfect, with added Professional/home drive scanning result comparisons with TRTs also from multiple drives, but if you think about the amount of effort/time this would require, you may understand why noone has published such a report publically.
Other optical review sites hardly cover more than the necessary basics when it comes to their review tests so it is hardly extraordinary that this article is not as comprehensive as some people would like. The article itself acknowledges this problem, maybe they will fix it in the future, unless another site is planning to show them how to do it properly.
