Also, If you put smaller buses on the 10/11, it will prompt more people to get on the 12, as people may be worried about not getting a seat, which will also lead to that bus getting standees (ironically).

And pushing more passengers onto 12s would then make the timekeeping problems even worse than they are already. 12/39 really needs at least 1 extra bus and additional running time (and recover time at Park End - from 2 minutes to turn around to nothing isn't helpful).
