Confusing?

Hello. Most people will say that the 399 has a PVR of 1 because that's the maximum amount of buses used on the route. Although, technically the route has a PVR of zero. Same with the 389 and W10. This is because these routes don't run in peak hours. I'd like to know which statement you think is true? Please just leave a comment or tweet me @LondonBusChaos. I believe that the 399,389,W19 have a PVR of zero and that instead of calling it PVR it should be called MAOBUITD (Most Amount Of Buses Used In The Day). Thanks for reading and please share what you think about the confusing PVR's/MAOBUITD's of routes 399,389 and W10.
