Raul: Obviously there are too many arms as well as arm lengths for each cartridge manufacturer to try. Also, I do not necessarily agree that a manufacturer needs to try different arms with each new cartridge they design. Those who have a great deal of experience designing cartridges already know what is needed.
I believe that some manufacturers tend to lean toward the conservative. That being said, Ortofon has been doing this longer than most and certainly are incredibly knowledgeable and thorough. But, I know what both my ears and both my eyes experienced... the cartridge was tracking like a champ with the combination we were using. This was not subjective. Also, remember the results were much closer to the lowest recommendation by Ortofon on the other two tables, one of which also had Reed arm.
The reason for this post was not to necessarily debate the point, but to have other Ortofon MC A90 owners share their experiences on the subject as I am sharing mine. I am not here to preach that everyone has to lower their VTF, I am only sharing that the possibility of doing so might yield similar results for those who try... or might not.
