Championship suggestion

In leagues where managers typically struggle to attend every race, have an optional setting to limit the number of races that count towards the championship. 
So for example in a 15 race league, if set at 80%, only a teams top 12 results would count towards the title race.withiut overly impacting their points haul 

Back to the championship of the 80s where this system cost Prost the title in 1988

I'm really not a fan of dropped scores. 
If people can't attend races either join a league that runs at a time they can attend or set up a league specifically for people who can't attend.
