GS Role rating vs FM Role ability

So It's going on for a while now.

Genie Scout showing different rating than the game itself.

The game changed position names that's ok but I think "Defensive Centre Back" is "Limited Defender" in GS.

So the problem is for instance I have "Shane Long" a regen. Genie shows that currently he is best in the role of Limited def, but the game shows only 8/10 on this position and 10/10 on central def.

So what is the most accurate? Genie scout or the game itself?

It'd be really helpful if someone could reply as this is one of the foundation why I use GS

GS 17 estimates role ratings differently than FM. It will be re-assessed in GS 18, including the naming.
