It means your possession will be 8% better than without this boost, but that doesn't mean your final qualifications will be +8% (because it depends also on other factors and your rival's possession stats).
Getting a 10% increase in an area of the game won't mean your team qualifications for this area will go exactly 10% up, it means they will be "10% better" in relative terms.
Condition bonus means your players will use less condition than they would for this match.
and this
@Jeeves :These days with my usual 8% Condition Bonus (Ye I hardly keep my bonuses at 10... Slacking off this season, meh. T_T), my guys barely drop in condition which gets me safely to the 2nd half where, after trying to figure out what my opponent ordered his team to do I decide to either go all out or be reserved and hold back as best as I can while trying to snipe a goal via some counterattack play.
are the proofs that training bonus either is cosmetic or has so minimal effect that neither the adms can't identify it.
@nikolgiorgos before long time explained his theory about the condition bonus.
That it reduces the penalty from condition loss, not reduces the condition drop.

And this is very easy to see during a game.
The avg condition loss in an official 90' game without using High pressing or Man to man, is about 22%.
Some players might loose 24%, some 20%.
Many times I used @nik's method to observe this.
I had an easy game and later an important game in Cup so I wanted to keep as possible high the condition of my players for the second game as I don't have a good 2nd squad.
I used the condition bonus during all the match, 5 times I think and saw that condition loss was exactly the same as if not using that at all.
I tried that many times and the result was the same every time.

I 'm not sure if the condition bonus let the drop be 21% instead of 22% but even that has a tiny effect for the game play or using that to save condition of players for a next game or training.
