If that is what we're looking at we may want to look at the guard elastics like OD vs JR that doesn't have any secondary connection or how high HA influences PA even though it doesn't train it through secondary training.
I can confirm, that HA>>>>PA boosts the PA-training tremendously. (I don´t have numbers, just subjective perception/experiences)
But your question is pretty nice, because I had some issues with the same question.
If we consider the fact that OD-Training also includes ID as secondary training we may ask, if a high ID might have an elastic effect on OD-Training as well. -> This might be useful for finishing training for bigmen, but also could mean that starting (after 1on1) with the BIG-Men-Training for a Guard could also make sense
And as mentioned earlier in this thread: 1on1 sets up the elastic effect for several other skills to develop.
JR trains as secondary skills JS + OD. Therefore, if the JS (boosted by
1on1/JS) and the OD (boostet by HA/ ID (?) ) are relativly much higher than JR, then a relativly quick development of the JR-Skill can be expected.
OD trains as secondary skills HA + ID. So a high HA (boostet by
1on1/HA/PA) + high ID (boostet by SB/ID/IS) is needed for a high elastic effect on OD. (Under consideration of the prior mentioned targets and time/trainingspeed limitations)
I like the idea you guys mentioned to use the first 2-3 seasons to train each skill to a certain level and set up the elastic effect by training 1on1. I think, I will prioritize this two steps with my new project.
PS: with my first SF project I trained ID-RB-IS-SB......the results/speed werent that great. Therefore, I´m with the SB-First-Theory and hope to get better results next time.
Nice weekend and regards
