If I understand the "Help" section correctly, these are two different functions. I may be wrong.

The 150 GB for a squad says:

"the progress of each player (1 day, 2 days, 1 week, 2 weeks), it is noteworthy that affect all aspects such as morale, but you will see an evolution exhaustive. You must have a minimum of 150 golden balls to activate this option, and will last 7 days."

I interpret this is as you will somehow see displayed a nominal value of the amount all your players have improved. eg. Player X has improved by 0.250 over the last X days. Again, I may be wrong.

The 10 GB for an individual player says:

"On this page you can see the graph of evolution depending on the training of each player. For 10 golden balls you can see a fairly accurate prediction of its progression over a lifetime (activated for 7 days)"

I interpret this (and know it to be so) that I will see the player's forecast and progression, but no information on nominal increase other than the graph.

Hopefully this is enough to answer your questions.
