The ultimate training post

Based on the post about CSR (see it here) I have addressed the topic of training. There are several questions to be answered:

1. What is the effect of Youth Academy training  over CSR?
2. What is the gain of a senior's training session in terms of CSR? and 10 sessions?
3. Is the training in the Youth Academy more efficient than the training in the seniors? When is it more efficient?

Assumptions

The starting point for this study is this thread in the NZ Offsite. This means that we assume as true:

• A level 3 session in the Youth Academy represents 0.20 of a pop.
• The skill levels in the seniors raise as per donkeysaint's table summarizing Tabac's study.
• Multiple sessions in the seniors don't reduce efficiency of training
• The CSR formula given in the previous post in this blog is true.

Training in the Youth Academy

What is the increase in CSR given a certain skill level?Let us illustrate this with an example:

A junior player has a stamina value of 12(12.00) and receives a training session; By how much his CSR is increased?

Answer: The CSR contribution of a skill at 12.2 - the contribution of a skill at 12.0 = 595

This is the increase in CSR of a single session in the Youth Academy:

Level 1: +1.4 CSR per training session
Level 2: +5.4 CSR per training session
Level 3: +14.8 CSR per training session
Level 4: +31 CSR per training session
Level 5: +56.2 CSR per training session
Level 6: +92.8 CSR per training session
Level 7: +142.4  CSR per training session
Level 8: +207.2 CSR per training session
Level 9:  +288.8 CSR per training session
Level 10: +389.8 CSR per training session
Level 11: +512.0 CSR per training session
Level 12: +657.4 CSR per training session
Level 13: +827.8 CSR per training session

As there are 4 training sessions with level 3 facilities and level 3 coach, that means the CSR increase of a weekly training in the YA is at most, 4 times the given figure.

Maximum CSR gain in the YA: +3300 (for 4 different skills at level 13)

Training in the seniors 

Using the CSR formula and having access to several players training 10 level 5 sessions, I have calculated the increases in CSR for a skill in the range 3-16 produced by a single level 5 session.
I express it in terms of fraction of a pop, to contrast with Tabac's table:

Level 3: 0.096 of a pop
Level 4: 0.091 of a pop
Level 5: 0.087 of a pop
Level 6: 0.082 of a pop
Level 7: 0.078 of a pop
Level 8: 0.072 of a pop
Level 9:  0.070 of a pop
Level 10: 0.065 of a pop
Level 11: 0.057 of a pop
Level 12: 0.054 of a pop
Level 13: 0.048 of a pop
Level 14: 0.043 of a pop
Level 15: 0.033 of a pop
Level 16: 0.030 of a pop

Comparing both trainings 

The following graph sums up this study



The conclusion is obvious: as long as the player is training skills above level 10, the Youth Academy training is more efficient than the senior's training.
