Not necessarily. If you train for the 1v1 specifically you will probably start training primaries after 1 season of 1v1, because the ultimate goal should be to get the best possible build in the 21yo season. The same goes for lower potential players, you really should avoid HA and DR eating your cap and focus on more beneficial skills.
To answer your question all the information is available in Coach Parrot and reflects the coefficients that were calculated with the US offsite project.
Specifically here I used the Calculators page and did things mostly manually. Most of the information is in the Coefficients page although the whole spreadsheet is not the easiest to navigate. Props to Jozef Ka for building it, but if I was him I would have named cell ranges for my own sanity!
