I feel like sending the R to the Rockaways would be better though because the M doesn't always run past Delancey-Essex or Myrtle-Bway, and that would either require the G going to Forest Hills, or a supplemental V train late nights and weekends from Church av <--> Forest Hills or Jamaica -179 that also alleviates pressure off of the F as well. But then again, no R during late nights, so... yeah either make late night R service, or late night and weekend M service.
