Just recently though, I've noticed that Versas allocated on the 36 have "every 12 minutes" on the rear of the buses, while those on the 42 have "every 10 minutes" on the rear. On the odd occasion, they've been mixed up. I'm just wondering if anyone has an idea as to which buses have each variation? Cheers

On a related note; based on Traveline, it appears the frequency of Sunday daytime 42's is decreasing from every 15 minutes to every 20 minutes instead.
