The PSA Type System: Should it follow the photography market?

[Jersey City Giants]

Here is a question I have been pondering even before this photo. If something is printed later but is not dated and the era of the paper is the same how do they tell? Take this photo. it is labeled 1914 but that is incorrect as the uniform is from 1913 (the only year they used Cubs on the road when he played with them) and its the Image from his 1914 Fatima. However, how would anyone know when the print was exactly made? Was it 1914, 1915, 1920, 1930??? And if the production is in doubt (assuming paper checks out for period) how could anyone render an opinion at PSA or anywhere for that matter in terms of its Type? It could be a Type I or Type II but definitively putting one of those labels on it seems just a guess to me. Again, I am just talking about the Type designation not anything else.
