Review 10-10-10-9 has internal game score 10 so it is highest possible it only means that you didn't enabled the Top review yet. It Has now other effect if you enable the Top review or not.

Perfect review gets enebled when you make bigger game (medium, large, AAA) and in that game you have assigned an expert to 2 or more missions (engine, gameplay etc.) that has development focus >=0.9, the same expert (only one) or more expert doesn't matter.
