Finals ..... FTD .v. Qualifying points

[Aire valley]

Currently Finals are sorted based on points scored during Qualifying heats ( rather than the normal FTD system ) the theory being that qualifying is smoothed out and rewards consistency rather than say 3 poor rounds but one very quick one i.e. FTD .....
Any pros /cons , preferences..?
Personally, I prefer the FTD system, but there is some merit in the current system.......not sure quite why it was adopted though..
