I'm sorry but 300% better? Really? Sounds BS to me, mostly because in my experience virtually all missed laps are a result of operator error ie the race director or driver. Consequently they are rare at any well run club and when they do occur its a result of something that means it won't matter if you are running RC3 or 4 - like when we got water in the loop box.
If there are more than 3 missed laps at a major meeting it would be a surprise, so how can one be 300% better?
RC4 won't mean less missed laps because RC3 doesn't miss laps when run properly. RC4 will still miss the same laps if the loop isn't right......
Anyway I can also say that a straw poll at Bury yesterday means we too won't be going RC4. Too many members with MRT's - and we have some nice handouts anyone with a Purcy can use
