If Pilots are team flying Results would also be similar since they have to be
fairly close to be of any use to each other.
In the standard class britsh pilots were 1st and 19th (out of 44)
15m class 4th and 37th (out of 41)
18m class 2nd and 3rd (out of 23)
open class 4th (out of 20)
From this I would deduce that team flying was only of use in the 18m class.

What seems to be having an influence in the UK is the number of younger pilots
coming along and 'pushing' the established stars.
