another split grade question

[NewMexican]

I learned split grade printing from Les McClean and I'm a bit confused. Does it make a difference which grade you expose for first? I know it's suppose to be soft then hard but does it make any difference?

Charlie, can you get the Mods to delete this duplicate? Split grade is always an interesting topic but if there are two threads then posters will split their answers to the same subject over both threads which is a nuisance when trying to follow the thread

Thanks
