From what I can tell every upgrate that mentions Energy Resoration gives another game your players can play.
This image breaks down how effective leveling facilities are so you can figure out the % gain per day. It's doesn't work on a % increase system rather you get more energy points to spend in a day instead.
Upgrading facilities is a linear gain and not a percentwise gain. 1 lvl in each facility gives you a flat increase.
I get the energy restoration part I am just confused if upgrading my Gaming house/gear increases the skillpoints my players gain per training session.
I dont remember the numbers but there are some.. i'll look into it.
.)Training efficiency correlates with your players Energy. Between 75-90% seems to be the sweet spot.
.)Energy has a higher impact on your training efficiency than 1 Lvl of gaming Gear (prop even 2-3 lvls but didnt test that)
.)There seems to be a random espect on training efficiency since a player got diffrent stats on 2 days while having same training schedule and energy.
if you found out something I would be happy to hear it :)
