Hey cool sponsor he has… In which country are you playing ?
As I told, I ‘m not sure about LV 4 yet but I ‘ll continue next season.
As I can see, those players have TR Factor
Yudin V 7600/ W 150=50,6
Vacek V7900/W150=52,6 so it’s about the same. Also same age and stars. Position doesn’t matter.
The top prices for my level, for 18 y.o. , 5 stars players is about 5M +, so I guess they from the top list of your level4.
1.I wouldn’t expect that difference in raise between them because they have same characteristics. I don’t know if the condition and morale were the same because it matters.
I believe that results in power training is a mix of (the original) TR Factor, condition/morale, age, STARS and maybe some uncertain factors like if the player had a game before 2 hours and you gave him a green booster. Then the system roll dice.
2.The results for Yudin is great for 5* and for Vacek also good.

3.I can see something that happens to me some times. One player gains more in Practice match and the other with similar characteristics gains after that, more points in cardio. Why is that ?
Roll dice result ?
Some trainers react better in practice or cardio or stretch ?
Some trainers have better results with fool green bar and others are better in light green/orange bar ? Can’t prove it, not enough resources.
Tank this season, you mean you’re gonna stay at lv4 or you’ll go to lv5 and stay there ?
I believe that having a fast trainer 5* and trying to tank it’s kind difficult. With my other team in LV1/season1 in which I want to stay, I’m trying hard to loose every match, having my youngsters in the game to get the skill points, find formations to have 20-80 (against me) and watch the game while not hurt my good players (I read that if your players are out of their position , the get injuries or cards and yes my player spit on someone.
But my friend Khris is specialist in that subject. Hey man, do you have some guide or thread “tanking and training” or should I right one later ?
