Punctuality of trains and buses in Hungary

I will be traveling to Hungary next month and I would like to know if the trains and buses between different cities are punctual or not. I am from Spain and here, in general, the trains are but the buses are not (due to traffic jams and similar stuff).

I've found this survey but it doesn't give me any information about buses (which I expect to be less punctual than trains) and the information about trains is also not very clear to me.

I will note that I still consider it to be punctual if it just involves a difference of a few minutes (up to fifteen minutes more or less) with respect to the established schedule. I'm just concerned with major delays.

Regarding trains, there's a joke about the Hungarian Railways (MAV): it only has five adversaries, the four seasons and the passengers. Weather related very severe delays are quite common. It can be a large tree branch falling over some tracks, killing the entire route. In the summer heat, there will be speed limits. Let's not even talk of snow. The system doesn't have a lot of redundancy built in. So, yes, normally trains will be punctual within 5-15 minutes but you need to pay close attention to up-to-date information which is typically only available in Hungary (for example, on http://www.mavcsoport.hu/ under Mavinform).
