Suggestions to overcome the new training system difficulties
1- buy 18 years 50-59% players instead of 70-80-90% and test if they are fast trainer or normal or slow trainer before you invest any rest
2- Hard train using 1 drill only until the targeted white skills become 150-160% or until u feel that the drill 1 is no longer bringing good result in regard of the rests wasted ... at this time start using drill 2 to target new set of white skills
3- Don't waste any rest on players at age of 22 and above
4- start hard training with drills that ONLY target white skills and use the drills that target 1-2 dark skills later ....
