Energy Values
The way it is now you have to do some testing every day to get behind the math of it, which given enough time and dedication will eventually happen or already has happended for some players but its not really "new player friendly".
You could for example put a description on the players-page that says "each solo queue game consumes x% energy, each steaming session y% etc. and put the values of facility upgrades next to the cost description like gaming gear v6 boosts training effectiveness by x% etc.
