Happy New Year to all!
Looking ahead at the 2018 calendar, with the new veteran system in mind, a question occurs to me that I haven't seen discussed yet (although I may have missed it!):
Is the ranking in the new veterans single division based on the best 3 events, as with 2/3 or the best 5, as with p/1 ?
Comments and clarification are welcome!!

Best 5, based on ACM Minutes

PS - In last year's year book B5.6.1 also says best 5 and does not distinguish between P/1 and 2/3. This is born out be last years rankings.
I think it has been that way for a while

Many thanks, Dee.
