If you have done the ten route sectors then the only thing you are excused is one route sector when you do your proficiency check. Now considering that a route sector is defined as take-off, 15 mins cruise and a landing, you will inevitebly do a route sector in your proficiency check, even if you don't need to. This means that there is practically no difference in the two different revalidation flights, regardless of how current you are. Another great system.
